Hi all,
I was washing the car the other day and noticed wee small splodges of black soot on the boot and number plate. I had seen this a while back not long after I got the car, so I put a bottle of injector cleaner in. It seemed to solve the soot but now a few months later its back again.
I don't know but would say thats a sign of the car running too rich, what do you think?
