Customer complaint CEL on. Went to Zone, they scanned said bad MAF, he put a used one on, same problem. We scanned, came up with 2 codes: P1166 - Manufacturer control fuel/metering code P0101 - MAF (A) circuit rug/perf
Thought I would post data stream to see if you can see something I've missed.
Throttle Position - 11% Intake Air Temp - 54* (close to ambient) O2 Sensor 1/1 Volts - .08-.80 Calc Engine Load - 14-16% Spark Advance 6-9* Fuel Loop Status - Closed LT Fuel Trim - minus 13.3% MAF 1.9-2.2 g/s STFT B1S1 - 25% STFT B1S2 - 99.2% STFT 22-24% O2 Sensor 1/2 - .75-.80V
If I had to venture a guess it looks like it is overfueling for some reason. And with that Manufacturer code, that sounds like a bad ECM. Can anybody help a feller out?
