I have a z6 supercharger setup, and I bought the car with the problem that it Idles irattically, it bounces between like 2 and 3.5 k rpm, ive checked up on a lot of things, the only code its throwing is for vtec, the map controller is not wired in yet could that be the problem? Also on the inside of the throttle body there are two holes (close to where the intake mounts) If one of the holes is covered up with my finger the car runs perfect at a steady 1k rpm about. Is this a shot throttle body? or is there a way to adjust it? Im going to work now but can answer qustions when I get home at 3. Thanks in Advance

 

sounds like one of your gaskets is bad or something isnt tightened all of the way with your TB or IM. it could be a shizit load of things.

 

I wired the map contrller and still have the same problem, should I just replace the throttle body?

 

has anyone had this problem?

 

Bump...........................Anyone???

 

i cant be positve but it sounds like you have a missing/defective fast idle valve or a idle air control valve, if you could get pics i could tell you which one you are pluging, ill look arround for a pic online

 

ill get pics later, but when i cover one nothing happens, when i cover the other the idle gets fixed, when I cover both thecar dies, ill have pics up in 20 min, need to get a camera. thanks
