Question about 2000 Pontiac Grand Am GT
My car idles fine from a cold start, but as soon as the engine warms up the it bounces like crazy between 0 and 1000 rpm's and eventually bogs out and stalls like its running too rich? could it be an O2 sensor messing up the fuel mixture? I had it put on a scanner by a mechanic that i know and i got P0446, P0449 both emission codes, i changed out the mass air flow and that didnt work either. Someone help me fix this issue! Thank you!
