Robert Hughes: I'm not seeing the solution to my problem no matter where I look. I've been
experiencing throttle issues with my 2004 F-150 5.4 3 valve V-8 98,250
miles. My truck idles fine, however, it has a "hesitation" when I'm driving
down the road. It's much like the old carb motors with that throttle
hesitation. It acts like it's starving for air or fuel. Sometimes when I
push down on the throttle just a little bit, the motor starts to "surge".
I changed out the fuel filter, used a fuel additive to clean out any
residue in the fuel lines, but to no avail. I'm wondering if the throttle
body is the problem or maybe something else. I get no codes which is why
the dealer says he can't help me. There's no recorded codes in the PCM.
What do I do?
Missy Mcbee: I have a 2001 Cadillac Deville, idles high we cleaned the throttle body
still having problems... Sometimes we drive it its ok and then it starts
again and when we put it in park Im scared its going to mess up the
Transmission, We're at a light or stop sign and it wants to keep going... I
dont know wht to do its costly...
DysfunctionalBubble: That's dirty? It looks nice and new compared to mine. My 2004 optra is
coated on the top visible bits with a darkish layer of tobacco colored
stuff. The sort of thing that you see in side of the engien on older cars.
I have no oil burning problems, so i don't know why its so dirty. It makes
this one look like it's brand new.
Paul Mansfield: I get this problem on my Ford Maverick (2003 model) - 2L engine, sold in
USA as the Ford Escape. Cleaning the throttle body solves a stalling
problem where the engine won't idle if you stop for a short while and try
and start the engine when hot. I am wondering if it's related to the
exhaust recirculation valve reporting a fault.
Natalie Cotero: Ok so I have a problem I changed the spark plug wires on my 2001 f150 4.2l
v6 2wd and I sprayed some throttle body cleaner and when I went to go start
it it killed all my power why is that?
jesus gutierrez: i have a 2003 Yukon that would die when making a turn, and it would run
rough at a red light, i saw your video and went out and got a can of
throttle body cleaner and an old tooth brush, I cleaned the throttle body
and replace the air filter and now my truck runs like new again!! it was an
easy and cheap fix, I spend a total of 23.00 dls. for the cleaner and air
filter, thank you for sharing the video
Team Alpha (Gaming): Should you not unplug the TB? I've heard stories of some TBs having a
mechanism to return the butterfly back to normal position, thus cutting off
any fingers in there :(
jleal11: Does the throttle body need to be calibrated after the cleaning since it
was manually opened?
Macmillium: I would be careful not to open by hand some electronic throttle bodies, as
it may not like it. I did that on a 2004 Titan and few weeks later the MIL
was on, the idle was very bad and acceleration was not smooth, so I had to
recalibrate the TB... Should had use the pedal with the key on as he
suggested here. Also not to use any cleaner as it may destroy the coating
on the throttle plate. In my van the pcv was never replaced, so by 150k
miles the whole intake was dirty, so I took apart to clean it up. Thank you
for posting this video.
MrSlackerSteve: Just going to say... many auto manuals explicitly state not to scrub your
throttle body with any kind of brush as it can remove a protective layer of
coating. Please check your specific cars manual but you would be better
served spraying with throttle body cleaner and wiping with a clean dry rag
to be on the safe side.
tigaspinoypower: Please help...My Honda Passport 96. while im driving and when stop sign i
got high rpm and when i shut off my engine and counted 5 sec. and i start
it went back to normal rpm and the following day same thing happen when im
onthe freeway and then was so traffic and i drive slowly and my rpm went
up. I just want to know if something to do with this with throttle body
k smith: hey guys husbands 2006 , mercury montego was recalled called ford got it
fixed for nothing some 650 . ford recalled them you don;t have to be the
first owner GO FOR IT,waiting for them to recall the tranny now
brillopad6901: I just had my computer reflashed and my throttle body cleaned on my 2003
Toyota Camry and it drives better (it was dying at a dead stop) but it
seems to chug when I get up on the gas, almost feels like one cylinder is
misfiring but I get no check engine light codes. Could I have a leak in my
intake? Should I replace the throttle body? I've taken it to 4 different
mechanics and they can't figure it out.
LoVeHa7e: Motor shaking car not advancing
Anyone know what this problem is. Maybe trustmymechanic knows
Marcus N: Why the hell would 14 people not like this ? "Oh god damn I hate a clean
throttle body.!! .grrrrrrrr "
J. Wilson Perez: hi i have a 1992 6g galant automatic transmission. we recently overhauled
it so i know.that the engine is having a high compression. the problem is
when the car is in Park/neutral mode it idle normally but when i put in
into Drive mode its suddenly stall from 900 rpm down to 600 rpm and goes
down to 500 when i turn on the a/c.. thanks in advance for your help..
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.
Sayed Youssef: I have a 1998 infiniti i30. Do I have to take the throttle body out to
clean it? is there any house hold products i can use to clean it?
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
RentonReturns: hey i have a 94 buick century and when im at a stop light or turn it
stalls, happen 3 times within 4minutes one day, any suggestion on whats the
J. Wilson Perez: update.. my car is now idling smoothly with aircon on. but still stall a
little bit when in drive mode. by the way i replaced all the hoses in egr
valve which helps a lot in idling smoothly.
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
prince keem: Ok so my car always idle at 1100 I just replaced my iac valve this morning
I cleaned the inside of the throttle body and plate and right when I
started it up it idled where its supoose to be at 700 but den 30 mins later
went back up to 1100 well I didn't notice a change in the way the engine
souded still quiet and normal but the needle was back at 1100 rpm at idle
should I replace my throttle position sensor also?would that help? already
checked for leaks and seafoamed my car i have a complete tune up also
J. Wilson Perez: update 2... all is working good right now like a brandnew car.. idle is
stable with aircon on and when in drive mode. no more idle stalling..
thanks very much.. godbless.. just one more minor problem. rear engine
support was broken but it was an easy fix.. anyway thanks again.. :)
Joe Mault: What do you use as a cleaner?
Otto Soldiers: Please help mu toyota avensis 2003 auto shakes or vibrate while on idle and
revvs itsself up nd downs, hen i stop at the red light or when driving at a
traifc it start shaking then later the check engine light comes on, it is
even worse when am doing reversing it shakes like hell no but when on
motion everything seems normal, what culd be the problem?
Kadeem duparl: OK so I have a 2010 mercury Milan and it's stalling and the check engine
light comes on, the rpm gauge also is jumping like crazy, do you think that
could be a the throttle body needing cleaning??
J. Wilson Perez: yes i adjusted the biss screw to compensate the idle issuues when in drive
mode and Ac on. do i need to check the Ecu?
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?
J. Wilson Perez: i tried it already cleaning the throttle body and replacing the idle
stepper motor with a working one. it idle normally when in neutral/park
mode. but when in drive mode it stall and when the aC is on..
Joe Lewis: I have a 2000 lincoln navigator when I turn the AC on my car will start to
shut off but if the AC is off my car run good
Andy D: 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?
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?
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?
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.....
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.
David Johnson: I replaced a throttle body on jeep commander but engine is still on should
I clean that rubber casket also
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
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?
Brother lee T.v: +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
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?
LCCharlie: I was surprised that you used a steel brush on an aluminum throttle body; I
would have stuck with nylon or plastic.
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.
