tigaspinoypower: Please help...My Honda Passport 96. while im driving and when stop sign i

Joe Mault: What do you use as a cleaner?
Tactician Craft: ings I've done to my Dodge Ram 2500, 5.7 Liter Hemi.
1. Replaced the Steering wheel pump.
2.Replaced the A/C Compressor
3.Replaced the Belt Tensioner..
4. Replaced the Power steering pump Pully.
5. Bought break cleaner spray and cleaned off all pully's just in case
Glycol got on them.
6.Bottom small Pully nearest the fan its a small one the back of the belt
rides on it cause its a smooth replaced it . This one was a strange one
though when I first replaced the Powersteering pump the original bottom
small pully was disintergrated I mean busted up bad, so far the new one
looks ,and spins great. This one still bothers me though can't figure out
how that happened.
7. Bought 3 serp belts so far.
-I'v completely hit a brick wall Don't know what else to do I'm not a
mechanic.The sound does sound like a pully and you can only hear it when
it goes over 1000 RPM's.and it is not consistent. WD-40 does not help. I'm
fixing to have a brand new engine with all the parts I've put in. Any ideas
would be appreciated.;
brittany p: can a throttle body stop your car from turning on? i have a dodge magnum
and she wont start. and if she does i have to hold my foot on the gas to
keep it on and as soon as i let go she turns off and it sounds really rough
if she turns on
Augustine Lopez: My minivan has these problems; very rough idling, exhaust smell and poor
fuel economy. I'm wondering if this will solve those issues and what kind
of cleaner are you using with that brush?
Rahman Kodiyil: i have got a strange issue with my Toyota corolla 2011 (auto
transmission GCC specification 1.8 )
i see a surge in RPM when getting to complete stop (AC is on )and i feel
the push of the car, as if it wants to accelerate and gets to complete
I notice this more when i drive in slow moving traffic where i have to
accelerate a bit a then stop.
The push or the jerking is more when i drive in D3 or D2 .
i have cleaned the IAC and throttle body, replaced my brake pads but still
has the same issue.
i don't feel much issue when the Ac is off , well there must be a bit but
cant notice it nor the RPM jumps or surge.
kindly help me way out of it.
blazzer73553: why did you not take the throttle body off and clean it? i feel like not
taking it off is a band-aid solution and will not allow a full proper
derrell lee: +TrustMyMechanic.com ive cleaned my throttle body a couple of months ago
and the rpms kept going up and down after cleaning , after awhile it went
to normal , few months down the line my idle issue is returning , is there
a certain procedure that you have to do so it wont do this
David Johnson: I replaced a throttle body on jeep commander but engine is still on should
I clean that rubber casket also
Marcus N: Why the hell would 14 people not like this ? "Oh god damn I hate a clean
throttle body.!! .grrrrrrrr "
VroomVT: My 1996 nissan 200sx idles weird but only when warm, and when going down
the road. If im engine braking, or lightly pressing on the gas, it will
jerk. Could this be my throttle body?
Silver Fox: 2008 mazda 3 auto. My car makes this loud humming/ buzzing, like a moose at
night sound when accelerating. It mostly does it with AC on but can happen
with no Ac. The noise increases with the gas pedal but would die down after
about 7 seconds. Any idea?
Voloria Hooker: My RPM is off the charts on my 2004 Cadillac CTS. When I start my car the
rpm shoots up to 4 & then will go up & down...The fluctuating RPM and the
surge and die thing at stoplights.... Going to try it tomorrow. Just a tip,
though. I was told by the dealership that I need to replace the throttle
body gasket & connector. Will the cleaning really help that much or is it
davidbdoucette: On a side note, I do believe you had a hitchiker on board. Look in the
lower right hand corner of the video for the first 30 seconds and you'll
see him hanging on for dear life, legs dangling. :-) May not be
responsible for your rough idling, and it is almost 2 years later now, but
you may want to check for nests.
Christine Kewallal: can I just say how much I appreciate the time you took in your about
section explaining the situation? 1 minute into reading through the
description and watching the vid, and I'm keeling over at how my situation
mirrors this. I'm going to find the cleaner today. Thanks again from
Andy Warren: Hi, I'm just cleaning my TB now on my Ford150. Should I put silicone on the
gasket or TB to make sure it seals properly?
Missy Jane Music: My car used to always have a low rpm, 20 max when accelerating to get on
the freeway or pass a car. Now the rpm hovers at a minimum of 5 rpm, even
when at 0 mph. It ramps up to 20 rpm when doing basic accelerating or
street driving. Could a dirty throttle be the cause or should I be worried
about the transmission? Thank you!
Luke Moore: i prefer to remove the throttle body when i do this so alot of that junk
doesnt run into the engine, is this a good practice?
Voloria Hooker: +Garrett Staats did the cleaning help? I have the same car and seems like
the same problem too!
Penfold8: I have heard that you shouldn't mess with the butterfly valve because that
will send the computer into a learning mode and will take a while before
the vehicle starts to behave again. Is that true?
LCCharlie: I was surprised that you used a steel brush on an aluminum throttle body; I
would have stuck with nylon or plastic.
Garrett Staats: Holy crap. This exactly what I have been looking for. I bought some MAF
sensor cleaner and it helped a little bit, but I think this is my problem.
The fluctuating RPM and the surge and die thing at stoplights.... Going to
try it tomorrow. Just a tip, though. If you run a K&N air filter, you might
have to clean the MAF every few thousand miles. Kind of makes me wonder
about the K&N filters.....
TrustMyMechanic.com: Yes it can if the throttle body is really gummed up with carbon. Also a bad
throttle cable can cause it as well. I would clean the throttle body first
and see what happens...it should be part of routine maintenance anyway.
TrustMyMechanic.com: Yes it is a profitable job for the shop, but most...if not all customers
will not or do not feel comfortable doing it themselves. Using cheap
gasoline, and just the nature of come vehicles cause dirty throttle bodies
more than others. Ford seems to be the worst when it comes to needing to
clean. Yep, good comment on the brake leak. If the fluid is low either the
brake pads are worn out causing too much fluid to remain in the caliper or
there is a leak.
TrustMyMechanic.com: Yes it could be and if you were in my shop it would be the first thing I
would look at...then I would check for a vacuum leak under the hood
somewhere. With the engine running, open the hood and listen for a hissing
type sound usually around the air cleaner fresh air duct work going to the
air filter/cleaner case.
TrustMyMechanic.com: Did I reply to your question???? If not, sorry, Yes, start by cleaning the
throttle body first, then if you still have a problem I would look under
the hood and listen for a vacuum leak (hissing noise) if you still have an
issue. Also make sure the "base idle speed" is set correctly.
TrustMyMechanic.com: Check the automatic transmission fluid, if low fill it up and check for a
leak. If it is full, then you have excessive internal wear inside the
transmission. If this is a standard shift, probably due for a new clutch.
TrustMyMechanic.com: Yes, I would start with cleaning the throttle body and see what happens.
Also make sure there are no vacuum leaks from any rubber hoses or hose
connections. You can sometimes hear a hissing noise under the hood with the
engine running if you have a vacuum leak somewhere.
Mabelle Montina: This is really helpful, thank you.
jeannie baker: Many years ago my 1968 Malibu would not start...The maintaince man at this
business came out...seen what my problem may have been. He left and
returned with a can of cola and and dripped it on my battery cable
connections... I've been a believer of this ever since. Too bad I didn't
view this first...my vehicle goes in for a throttle body cleaning tomorrow.
Least wise they will stand by on their word for the job. My vehicle is
getting only 135 miles per tank full!
superchunkwii: Thanks for the video! However, you're holding your phone wrong. Needs be
horizontal when using as a camera, not vertical. Your TV is horizontal
DGJunkie1: I got a code on the #3 cylinder today for ignition problem. Thought it
might be the coil but I checked the plug first. The plug was only held in
place by two threads. Easy fix. I'm still gonna clean my throttle body and
replace coils and plugs soon. Almost 100k miles time for it anyways.
TrustMyMechanic.com: No I dont think so. If the engine speeds up (RPM goes up) but the vehicle
does not move then I would suspect an internal transmission problem or a
linkage problem not engaging the transmission. If transmission fluid is
full, then there is not much you can do except pull the transmission out,
or remove the transmission drain pan for inspection.
TrustMyMechanic.com: I think cleaning the throttle body would be a good place to start, also
check to see if you have a vacuum leak somewhere under the hood...any
rubber vacuum hoses broken or unplugged? Sometimes you can hear a hissing
noise under the hood with the engine running in park.Your mechanic should
also check the PCV system, I have seen these cars get plugged up with oil
sludge causing idle and running issues.
WHINEUP1: Could a dirty throttle body cause the gas pedal to feel stiff, or make
takeoffs jerk forward when pressing down on the accelerator pedal ?
Marilyn Gines: i have a 99 ford escort and it keeps on turning off while driving it. i put
it on P and turn it back on and it keeps going but it does the same thing.
we put in the diagnostic scanner and it read the the IAC valve needed to be
changed. we changed it and it still turns off. are there any other parts
that may cause the car to turn off? i would appreciate your help thank you!
MsCerise007: I tried to put my car in reverse & I did but it wouldn't back up it rolled
down the drive.I put it in drive & it would not go forward.The fan belt is
fine so I checked oil, transmission fluid, and power steering fluid & they
were all full.Car starts fine just won't go forward or backward.I have not
had transmission problems or any problems at all. What do you think is
going on? I have a 1993 Ford Tempo.
juicy9600: please respond back. when driving sometimes my car will jump/lunge forward
then in park the car wll idle high up to 3k rpm once I was driving and it
completely cut off kia told me they couldn't find a problem took it to
another mechanic same thing told me my car has to be idling high when I
bring it in ive google my car symptoms and come across it could be 1.
throttle body or failing idle air control 2. throttle position sensor 3.
vacuum line going to the valve cover has a leak
TrustMyMechanic.com: It could be a vacuum leak, or could be a problem with an injector or the
fuel pressure regulator. A bad injector or completely clogged injector can
cause a miss (although I rarely see bad injectors anymore) or a leaking or
bad fuel pressure regulator can cause lack of fuel pressure which can feel
like a miss sometimes. Last thing, I would do a compression test on all
cylinders to make sure one cylinder is not damaged or weak compression.
Charlie McCollough: Hi, I seen that you were answering questions about people's car problems so
I was wondering if you could answer one for me...I have a 99 ford explorer
and it has something that rattles underneath it, now its 4WD and when I
turn the 4wd on and engage it the rattle stops completely but then when I
turn it off it starts rattling again, do you know what might be the cause
Sergio Martinez: remove the throttle body of a 2004 bmw and clean i move throttle plate with
my finger , i have to reset it and and how
Videl Burden: It starts fine and I took it to OReilly and it had a engine misfire in
cylinder 6 so im guessing its that injector but its a very expensive
TrustMyMechanic.com: Yes it could be, anything that places an extra load on the engine (like A/C
compressor) will cause a slight decrease in idle speed and if the throttle
body is dirty the idle can surge up and down until it finds neutral
ground....if it can. Also make sure the "base idle" speed is set correctly.
If the base idle speed is too low, any additional load will bring the idle
speed down to low and will have trouble maintaining a smooth idle.
AL M: profitable job for the shop. I've run trucks for 350,000 km in dusty
conditions without ever touching the throttle body other than cleaning the
isc motor. I sure wouldn't pay to have the throttle body wiped out. To
TrustMyMechanic The guy with the bad brakes had better go to a shop. First
I would check if there is brake fluid in the master cyl. if its still full
it won't be a leaky wheel cyl or hose it will be a bad master cylinder.
JSBPisgah: It's good to clean a throttle body, but beware...it can really mess with
your idle. Unless you want to do an idle relearn, approach with caution.
TrustMyMechanic.com: Yes, it could be. I would clean the throttle body and idle speed motor just
as maintenance and see if that helps.
ThePariss333: If this part get dirty, what is the purpose of an air filter? Its not the
air filter inside to give clear and clean air? Why this part get so dirty?
This is a good question I haven't see around youtube Maybe for another hose
getting there and bringing dirty things?
oleg1981: can the build up be a reason of no starting at very cold weather! like -4F
or even colder. but if you give a little push on gas pedal its starts. its
2006 equinox with 180000miles. everything is electronic there. when it
warmer outside there is no problem starting.
kamikaze: I have a 1999 toyota corrolla and my rpm is fluctutaing but also rpm drops
below 500 when engine is warm. Is this still the same problem?
