My Car won't stop idling funny. Its idling up and down.Even after is warmed up..

This is what i have:
d16y8 motor
p28 Ecu Virgin
Obd 2 Dizzy


I'm not getting any codes from my ecu.

Are these lines right ?

Should these be capped?




Please help I'm lost.

bump

 

hm i could be wrong but that red hose coming off the canister looks like it might be hooked up to the wrong place?

I believe thats right.

 

if your idle is going up and down it mite be your IACV = Idle Air Control Valve, or something like that.

Isaac-

 

I bet you got a vacuum leak where the intake manifold bolts up to the head....

 

I adjusted my idle screw all the way down and it some what stopped it, but it still doing it. Any Ideas?

 

Also, when I first start my car it doesn't do it. When I'm driving and then stop it does it for about 10 or 20 secs and then it stops..

like i said, its the little sensor on the back of your intake manifold

yes, i did and just messed with the idle a little bit, BUT make sure when you do mess with the idle that the car is WARMED up cause if you do it when the car is cold your idle will be fucked up. the only thing that sucks about doing it this way is if you live where it is really cold and you go out to start your car in the morning you will have to turn the key and the give it alittle gas so it doesn't die. by unpluging this sensor you have No cold idle state

 

Make sure you check everything for a vacuum leak first.

 

replace the iacv. if you want swing it back by the shop and have harvey check it out again. but i believe it is the iacv.
