I have had this idle issue, for a while now. and I can't crack it. my idle keeps searching the entire 1-2k spectrum and wont stop. the car gets hesitation when starting to boost. Im sort of clueless where to start and this problem seems like it should be able to be taken care of by someone around here. Id rather avoid traveling 5 hours 1 way to Banzai to fix this problem. If anyone can give me advice, or if anyone local (oakland county) wouldnt mind giving me a hand or checking it out. I would be VERY grateful. I have been unable to work due to being the caretaker in my family. so at this point in time money is slim, but.... enquire please.

 

search "hunting Idle" , I had the same issue after I installed my Power FC, you need to adjust a screw on the underside of the throttle body that adjusts the air intake. For me it was all the way in and i turned it counter clockwise approx 1/3-1/2 a turn.

 

ive done a lot of searching but never heard of t hat screw, do you actually mean UNDEr the throttle body?? like removing the plenum? or just on the lower side, I know theres a few adjustment screws for the idle. but I didnt change anything with the car. it juat suddenly happened.

no need to remove anything just adjust the screw

HOWEVER if this started happening with no changes on the car others more knowledgeable on the forum may be able to help you out more...

hop this helps
