i put a b7 intake on my y7 and converted the iac plug to a 2 wire and moved the pin in the ecu to the 12 spot and now my car wont idle unless i have my foot on the gas any help would be great!!!! im running the factory p2e ecu

 

Did you replace the throttle body as well, or did you just bolt the Y7 TB on the B7 IM?

 

i used the b7 throttle body and iac

 

Check your throttle cable tension (it should have some play with your foot off the gas pedal). Also, check to make sure your throttle plate isn't closing flush - if someone fiddled with the stop screw, you're going to play hell getting it to idle right.

 

adjusted the stop screw and tps and it idles better now but it has a stutter at minimum throttle application now

 

Any CEL codes?

 

iac bad circuit

 

still have a fluxuating idle at about 1500 rpm and the power lurches at low throttle
