if youre having idle problems one thing you can do is take off the intake and spray some throttle body cleaner (from crappy tire). i know that helps rough ldling but other than that i got nothing lol.

i would start by checking the IACV, then move onto checking engine vaccum if the problem persists.

ok i goot that IACV off and it was all dirty i cleaned it up and started the motor now the long revs stoped instantly now they are little short revs from 900-1200 and i got code 14 flashing on the ucu so i need 2 look that up now

ok i forgot 2 put the wire back on thats why i got code 14 and now the rev thing is stil there

Generally if the idle levels out once the car is warm, then the first thing you should look at it is your Fast Idle throttle valve(FITV). It adds more air into the intake when your car is cold to get the RPMs up to help warm the car up faster.

Take is off of the intake manifold and spray it out with brake cleaner fuild.

You don't have to rip off the whole intake manifold either.. if you can get your hands in there, take it off just like that..

ok thanks i wil try this


i changed my IACV and stil the same old **** so then i got a throttle boddy code on the ecu so i changed the throttle boddy and stil save reving iratik


so then i sprayed break cleaner at the intake were it conects 2 the block and the engin rev changed so i think i could have a vacume leak in the seal so its being changed tomorow but i wil see if i can get that thing off tonight and clean it up thanks guy il let u know how it goes





AT 1ST IS STOPED WEN THE CAR GOT WARM NOW ITS ALL THE TIME

if you sprayed it near the intake manifold gasket, and it the idle changed, you need a new intake manifold gasket

Don't go changing big things right now. Eliminate all the minor possibilities before spending a lot of money and time.

well an intake manifold gasket is cheap and pretty easy to replace and if the idle changed when he sprayed some schmegma near the IM gasket then clearly there is a leak.
