Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Is it No.5 or No.6, your info above says 5 then 6?
Have you swapped everything including the injector to other cylinders, and it still misfires on this cylinder?
Have you done a compression test with all spark plugs out?
You say engine mount replaced, and now misfiring on cylinder 6.
Only one mount or both, if only one, which side?
Is this a V8?
Do you still need help with this misfire problem?
I hope my advice has been of assistance to to you.
