Running lean after CAI and muffler delete

nandosman

I had the same issue as you after I put my stillen CAI, FI Exhaust and test pipes, limp mode, same codes as you. I would clean maf sensors multiple times and the problem would go away for some time, and then come back. In the end, I cleaned my MAF sensors, and my throttle bodies and that fixed the issue for me.
