Hi all, i have a problem with my car that needs to be sorted but not sure what it is. the car seems to be overfueling,missfireing,backfireing, the fault code said rear o2 sensor was faulty so i replaced it (not cheep) and the car is still the same, the air flow sensor has also been replaced, can anyone shed some light on the subject?
cheers Daz
