Did this video help you?

Jeremy Boney: I am going to try this on my subaru impreza 06 rs I am having idle issues and am starting with the cheapest first. Anyone have a great safe throttle body cleaner brand for my unusual boxer aluminum engine?

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?

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.

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... 

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.

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 :( 

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?

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 symptom? Thanks

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.

k CARVING: 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 

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.. godbless

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 stop. 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 Toronto!

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 problem? 

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?

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?

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 more precautionary?

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?? 

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? 

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?

Voloria Hooker: +Garrett Staats did the cleaning help? I have the same car and seems like the same problem too!

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

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?

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?

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?

Brotha 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 

LCCharlie: I was surprised that you used a steel brush on an aluminum throttle body; I would have stuck with nylon or plastic.
