I have recently noticed black spots on my rear bumper and tailgate. I have read a few posts on here trying to fix the problem. The car has a mani and air filter I have recently changed the fuel filter, spark plugs , thermostat.
Its not burning oil and the black spots don't smudge they just wipe straight off. I think it may be overfueling. Will a new O2 sensor fix this or could it be something else.
I wanna get this fixed so I can get on and respray the car cant be dealing with black spots all on the back.
Cheers
