I installed a C&L racer intake on my '05 GT and with that I installed the racer tune and now my car keeps popping trouble codes for idle, OBD III read problems. Has anyone out there installed these on their GT and if so have any info to help solve this issue. I have put the factory tune on and then rebooted the Diablo tuner, reset to original settings and still have the same issues. Any help would be great, thanks.

 

what are the codes

 

Double check MAF install and plug connection
and that there are no air leaks in tube connections

 

So it didn't do it before the install, and after you took the install back off it is still doing it? Yeah codes would be real helpful.
