I got this nagging issue with my '08G8GT....My Check Engine light comes on regularly...definitely not the gas cap. I had axel back exaust mod's which really just consist of changing the existing mufflers to Flow Masters. No other mods have been made, yet. She also runs a little rough a idle which leads me to believe a Vac hose connection may have come loose......Any ideas???or has anyone else had tis problem.

Not yet, My first thought was the petrol cap but since you have checked that I suggest going to your local dealer mate!

Had the local AutoZone pull the codes.....Mass Air Flow error, all fingers point to the new exaust system. also, I am in the market for a loader/chip for this car and have had no luck finding one. Any one know where I can purchase one?

Check out VectorMotorSport! They have a very nice ECM tune that will give you about 25-40hp gains with a CAI mate.
