Hi guys, I'm having issues with my stock 04 liberty gt. It runs rough at idle and also noticeable on cruise control at 70 kmh. no fault code displayed. Car has had a full service, plugs replaced, faulty ignition coil replaced. I took it to the dealer last week for his 'expert' opinion, he said the air flow meter was faulty (reading high voltage). I replaced it...no difference, i haven't had the ecu reflashed since putting in the new MAF, do i need to?
6 months ago it threw up a code, replaced the front o2 sensor...could the issue be related?
Thanks.
