what maf are you running? we need more details.

Check MAF
TPS voltage
Vacuum leaks.

Then your could also clean your IAVC and try stable the idle with the idle screw.

Cleaning the IACV isn't a bad idea.

ok tps is fine,mafs fine,how do i test my iac valve?i unplugged it at idle and no change did not attempt to dive it like that.im reading that it causes the symptoms im having and id like to try testing and cleaning it but cant find anything on it for my notchback.any ideas?

[Kr5Kouki]

remove the iacv and spray chokespray or carbcleaner all on the spring, and the adj. screw needs to come out so its flush with the casing

[jin3001]

cool did that and the prblem persists although not as bad at least for the 15 min i let it idle....is there any way to test the electrical connections?i unpluged them while running and nothing happened...should it be that way?how do i know that its working?

[jin3001]

what kind of bov are u runnning. i had this issue with one of the ebay turbo xs bovs cause it wouldnt stay shut. I went to a greddy type s and a flange pipe that was solid alum and it runs fine now. Check your couplers you might have a leak somewhere. Good Luck
