Not sure how scientific this is but it worked for me.. I suspected th MAF, but when I unplugged the Lambda sensor the car ran better but not perfect. I fitted a new Lambda sensor and the car is now ok.razwanali said:Hey guys,
Wonder if you could shed some light? Have been reading all the threads on here re: erratic idling. Just wondered is there anything I can do to check that my MAF is muffed before i buy a new one?
