MAP code A friend just finished doing a cam (224r), LS6 intake, and header install for me. He said its running rich at idle, showed a MAP code. I told him I thought it could be a bad MAP sensor (used the one that came with the LS6 intake) or a broken wire at the MAP connector. Anything else we should check? What kind of voltage should it be reading at idle? Car is a 99 z28. was stock except for air lid and handheld 93 octane tune. My handheld has a tune in it for a cam with 220-230 degrees of timing that we're going to put in tonight.

Where is your desired idle speed set and what kind of kPa's are you seeing at idle? It should be close to 60 assuming your in the 800~900RPM range. Typically, kPa's will increase as idle drops on larger than stock cams...
