okay so i cleaned ou the tb today and put everything back into its place started the car and my rpms are 1800-2000 at idle they don't slowly drop down to 800-900 where it would idle before and when i press clutch in it wants to jump up about 100 rpm. when i give it a rev i noticed it takes longer than usual to drop back down. i have no CEL there isn't a vaccum leak. the only thing i can think of is that it needs time to relearn. i haven't disconnected the battery yet but i did unplug the computer and replug that and it didn't help. anyone have an idea for me to try and resolve this problem

having same issue, for a long time now, hasn't gone away, i'm curious to find out the cure for this as well

have you bought it to the dealer and have them check it out

just disconnect the battery for like 5 mins or something.

If resetting the battery/pcm doesn't work, make sure you did not bend the throttle plate. If it does not sit flush when closed, you'll get a high idle.

air leak?

dabalt4556

just had the battery disconected for about 10mins still the same. Its like wiping before you poop, just don't make no sense.

make sure the blade dosent hit the sides at all it will allow more air in

nothing is wrong with the throttle body its something with the computer or a sensor

u bent the plate. happened to me. go to the dealer if you have warrenty if not buy a new tb.

That throttle plate has to close flush or the high idle problem will occur.
The pcm comands it closed and zeros the position of the throttle plate on startup every time and if it is not seating properly to much air will get in and raise the idle.
It doesnt take much.

just an update i took the car to the dealership and the did a dianostic on the car then relearned the computer that worked for a whole 5 mins so they ordered me a new throttle body they believe that the carb cleaner i used damaged the idle air and throttle body position sensors so i'll let yall know if thats what happened. and of course they wanted to blame the injen intake i had before they did the dianostic.

Theres no way that ruined your TB unless you were spraying it all over the place like a maniac.

dabalt4556

i know it didn't bc the new tb had the same thing going on. so they just tuned it to not idle that high.
