Question about 2003 Pontiac Grand Prix
I have a 2003 grand prix gt with a NONsupercharged 3.8. it was throwing 4-5 codes about a month ago... i replaced the parts called for, including, O2 sensor, MAF sensor, plugs, wires, and cat converter... until i discovered a hole was somehow melted in the intake manifold. i replaced it and had to re-replace the cat converter due to it getting burned up from driving it with this problem. everything was fine until today. now the car barely starts and will run at an idle or slow acceleration for a few minutes, then stalls. if i unhook the MAF sensor, it runs, but not efficiently. i do not think it is a MAF problem, just something else disguised as one. please help!
P0102 is ---- mass or volume air flow circuit, low input.
Check the wires going to the maf sensor and at the connection. If all seems ok, you might need a new sensor, seeing how it ran a little better when disconnected.
