Codes came back yesterday. Hooked up the durametric and found that the TRA's were trimming fuel (-.36) so the car was running rich at high RPMS. Pulled the MAF from the my SPB, installed and the car ran great. On the left is the SPB maf, and on the right is the DD maf. Notice the browning at the curvature. The DD car came with a K&N air filter, which I'm guessing had been over oiled at times, causing the buildup on the maf. Cleaned it again and it's back in the car, if the code comes back again (which I'm guessing it will), time for a new maf.
