Alfa 156 running problems Like a misfire
I have an alfa 156 1.8 t spark and it is not running right it sounds like it has a misfire i took out the coil packs and found allot of oil in the spark plug recess of cylinder 1 which has damaged the coilpack so i replaced them all with genuine alfa units but the fault is still there so code read it and found
P0130-lambda 1 sensor,
P0300 – ignition failures (generic),
P0301-cyl 1 ignition failure and
P0304-cyl4 ignition failure.
Now I would have thought the P0300, 301 and 304 suggests this is the likely area of the fault, The Coil packs are new any help would be great.
i tried disconnecting the mass air flow sensor but that just made the car stall i also tried disconnecting the coils one by one everyone made the misfire worse
