vehicle judders on accelleration i took it to a local garage who hooked it up to a computer it said (multi cylinder miss fire) he said it could be anything then descided it was my timing chain £550 worth of job. i took it to another garage for 2nd opinion he said it wasnt the timing chain but was the air flow meter this has been changed along with the spark plugs but alas it is still doing it . has anyone had same fault if so what was the problem
multi cylinder misfire sounds like coil pack breaking down under load therefore poor sparking effort or cam position sensor is grubby. see if you can "swap" a good known coilpack first then see if cam sensor is bolted up tight or not
