Out Of Idea's

[dooky]

Hey guys been havin a bit of trouble with my car.

When at a stop car has a horrible idle, any where from 900rpm to 100 or stall.

Have cleaned aac valve, stock plumb back bov, had a different afm on there (tho was old and could have been crap)

I am buying a new fuel pump this week as well (if that has anything to do with it)

Does any one have any ideas what this could be?

Thanks for replys in advance!

did it only start playing up since you cleaned the aac valve? idle may not be adjusted properly

did you also clean up the cold start valve? thats the one under the throttle body.

also sounds like its a good possibility you have a vacuum leak.

I dont really know what maintenence has been performed on the car but if it were me I would be starting with the spark plugs...pull them out and check general condition gaps etc..then as I am reassembling all that I would pay close attention to the coil packs, any corosion on the connection where it meets spark plug ? squirt of WD40 may help.....good starting point as I am thinking if its a fuel issue you would have problems under load.....Unless you got a partially blocked injector or something...but start with the spark...I think the problem is there

it also stalls if slowing down to a stop and i put the clutch in sometimes. its more hunting then anything (can see the boost gauge rise and fall on vaccum??)

Ignore the engine vacuum fluctuating; Its an after effect to your issue, not a precursor.

it was playin up before i cleaned aac valve, thats why i clean it. how do u mean its an after effect?

i got the exact same problem on my n/a, i have cleaned throttle body and aac no fix yet.. also i changed the fuel filter and oil.

could it be o2 sensor?

[QWK32]

nah, wouldn't be the o2 sensor. i'm still going with vacuum leak. have you had a good look around for a vac line that isn't connected or a split in one of them? also did you set the idle after cleaning the aac valve?
