I'm trying to chase down a problem I've having after moving my MAP sensor over to the RH fender and wiring it to the stock plug. I have a digital dash car and used Casper's adapter to use the factory wiring. Because I have a digital dash, that plug on the RH fender was previously unused.
After I moved the MAP the car started running stupid rich and can't control the idle. In a strange twist of events, both the CTS and the IAC valve failed at the same time. I replaced them both and now have coolant temp values but still can't get idle below 1,100 after closing the throttle blade all the way.
It's acting like it has a ginormous vacuum leak, which is entirely possible, but I haven't been able to find it yet. There is a suspicious whistle at part throttle (no, it's not the turbo - sounds like air).
I want to eliminate the MAP as a possiblity. kPa at idle (1100 RPM) is in the high 30s. What's yours?
Thanks,
Jim
