Dc2 idle problem

[lukas]

hey guys,

my vti-r idle has been playing up..when ever i come to a stop the car will idle at 2500rpm than after a couple of seconds it will idle normal again..or some days it sits at 1500rpm or .200rpm while idling and feels like the car is going to stall..does anyone know what this could be..

by the way i have cleaned the throttle body,cleaned the iacv,and the pod..

also if it helps the car sounds like it has been sucking alot more air than normal..

any help would be much appreciated..

[OMG.JAI xD]

u missed out one valve there.

the FITV.
Fast Intake Temperature Valve. (i think -.-")

but there is another valve in there.
it controls cold idle.
could be stuck and not letting the iacv take over controlling the idle.

i have the exact same problem with my civic...
not all engines have the FITV, depending on the year..
if you figure out how to fix the problem let me know, ive had this problem for a long time..
also i mite suggest checking all ur vaccum lines

Check the hoses that conect to the TB. i had the same problem and was one them was loose.

i had the same problem with my s15.. though it was not idling at 2500rpm wen i come to a stop.. it will drop below 1000rpm and sit on about 200 rpm n go on mood swings..

it happened to be my air flow and wiring had it all fixed at the mechanics (it took me 2 hours to get there from the constant stalling from the revs dropping, also wen i was driving it stalled on me at 80km/h on a highway), now it drives smooth like its meant to be.

edit: also my mechanic did say the car was sucking more air than usual

i think your brake booster may have a leak or bad check valve.
IT happens , when you stop as your foot is on teh pedal right ?

[lukas]

yea its only when i stop at lights or what ever its fine when i start it up..thanx for that ill get it checked..do you know the best way to do it your self or should i get a mechanic.

oh by the way i have noticed my abs light has been coming on everyday for 20mins..so does this have anythink to do wiv the brake booster
