about a week ago i cleaned my throttle body and ever since then my idle is really high between 2-3k. ive been reading through all kinds of topics that ive searched on h-t and yesterday i cleaned th IACV and still i have this high idle. if im coming to a red light and take the car out of gear the rpms will stay @ 2-3k if i blip the gas pedal they will fall and idle just like normal....its almost like the butterfly is sticking just a hair ....any suggestions....can i put any lubrication where the butterfly closes @.....any suggestions would be appreciated

Try adjusting or cleaning the idle screw valve.

 

yeah also make sure ur throttle cable is not binding

 

it has some slack....i was messing with it a little today....and its been surging up and down....so i unplugged the iacv it idled great....so im thinking maybe to try and clean it again..? should i spray some kind of lubrication on the valve itself?(not in the screen)

 

i have the same problem but it would only go up to 1.5k-2k rpm..is there a way to fix this??

fast idle valve... search it on here or google

possible vacum leak

 

my throttlebody doesnt have one(fitv)

 

when u cleaned it did u take it off or leave it on car? if u took it off did u use new gasket?? did u unplug the Idle air control valve when u did this? what did u use to clean it and how? did u mix the tps and map sensor plugs up? any check engine codes?

 

i took it off the car....reused old gasket....and i unplugged the iacv and reset the ecu after.....the throttle isnt sticking anymore but i have that annoying idle surge almost like a vaccuum leak...but i cant seem to find one.....can the iacv cause some sort of leak?

 

get a new gasket for the TB. if u took it off its prob not gonna seal again with the same one.. and check to make sure u didnt get the sensors soaked in de greaser or somethin. but its prob ur gasket leaking air causing a vac leak the iacv has a rubber o ring gasket.. check to see if its still there if u took it off.

 

didnt take the tb off..... just iavc...it still has the gasket on it....

 

maybe its too dirty inside and stuck in one position? ive had to bypass the iacv b4 sometimes its easier than finding the real problem which alot of things could be causing the idle to fluctuate.. but finding the problem is the right way to go.

 

i think its the iacv bc when i unplug it everything is normal.....so aggrivating

 

what did you do with the iacv?

clean the iacv...

 

i cleaned it twice...one with brake cleaner....and then again with intake cleaner......its surging like i have a vacuum leak or something
