2000 grand marqui runs good cold /rough after warms up
my car runs rough and acts like its missing it wont do over 30mph or climb a hill,i replaced spark plugs mass air sensor fuel filter and 4 o2 sensors.my car only has 56000 miles on it and im the second owner ,the codes still say running lean bank1 sensor2,bank2 sensor2 this is my only way to get around and I live in bfe......someone plz help
Likely it's the MAF but without watching the actual readings coming from the engine sensors, it's only a guess. There's more to it than just reading codes.
ty tracy like I said it has a new maf I am trying to find someone with a cpu ,its just odd it runs great cold after an hour or so it starts running ruff im also going to check the fuel pressure
