Hello everyone, I live in Tunisia.
I bought a chevy cruze 6 months ago,
it displayed the following errors: P0137, P0300, P0302 and P0303.
So I changed the 4 spark plugs, still the same messages.
I changed the 4 spark plug cables, still the same messages.
I replaced the ignition coil, same thing.
I also changed the oxygen sensor 2 after the catalytic converter. The oxygen sensor message has disappeared but still the same cylinder 2 and 3 misfire.
PS : Mileage : 108.000 km
an idea please
