I have a 2005 Pontiac Grand Prix GXP just cleaned throttle body now it has high idling and it accelerates by itself now without me having to give it gas.

[@CadillacDriver]

You've obviously done something wrong. Check to see if the throttle cable or and linkages have been compromised or pulled too tight.

Hie I’m having the same problem on my Chev Cruze f16d3, cleaned throttle body now the car revs itself nonstop, I’m stressed. Did you find any solution yet?

[@edgarrodriguez1883]

Do you have a video where you replace it?

i have e36 320i engine cutting out when slow down top stop

[@sotheamam1244]

I try new idle air control valve still didn't do anything different. Truck still shaking. Am thinking it might be head gasket cause I had the truck running for 4 hours . Cause i was in hurry and forgot to turn off tge truck. I came back the radiator was melting but the truck was still running during this time. I replaced radiator and sits for 6 months and now i got to run for one week. After that it shaking now.

I also had a problem with the idle speed air valve. The car (hyundai getz) shook when standing. Irregular acceleration, smell of fuel and soot coming out of the exhaust. Fault codes p0130, p0134, p0171 alternately appeared. At first the garage thought it was an oxygen sensor and replaced it. The problem continued and the fualt codes returned until the idle speed air valve was replaced. Funny because I searched and searched on the internet for the fault codes that appeared and nowhere did it say that the problem could be with this valve.

[@garyesada5766]

[@StanleyHarper-nx9fk]

[@StanleyHarper-nx9fk]

It started after I changed the oil

[@MrEpsilonZero]

Thank you. Is this a BMW with volvo steering wheel? or two different cars....

[@MechanicBase]

Two different cars😁

[@AbsurdVisuals]

Excellent explanation, thank you.

[@mikefuller928]

I put a new idle control on my car and all oxygen sensors and I still going to rough idle and losing speed as well

[@louarmstrong6128]

Could be coils, or plugs or fuel pump, or vacuum leaks,

[@StanleyHarper-nx9fk]

I have a code p1636

[@MechanicBase]

Hi. Which car? This is a manufacturer specific code, and means differently depending on the brand.
