Hey everyone!
I bought a 2003 GT last summer and I've had recurring problems with DTC codes that I can't seem to fix. The car has been in and out of the tuner shop several times and yet my check engine light is back on again! The car has a BBK CAI, BBK long-tube headers, and looks to have a single cat chopped into either side of the exhaust. Here are the codes I've received over the past few months: PO151, PO171, PO153 and the most recent codes are P1151 and P1131. All four 02 sensors have been replaced and the mechanic but a custom chip in witht he MIL eliminators but I'm still getting the check engine light. The guy at the tuner shop said he ran through the car top to bottom, put it up on the dyno and tuned it, and if the light came back on he'd be all out of ideas. He did mention that he thought the long tube headers were messing with the O2 sensors and that my only two options would be to physically move the location of the O2's by drilling new bungs in the exhaust, or put the stock manifold back in, which there's no way I'm letting that happen. According to him, the car is actually running better when the light is on, but I just want it to go away. Anybody had a similar problem or no a quick and hopefully not to expensive fix for this? Any help would be greatly appreciated!
