My bad, I swear I read that if it was tuned it wouldnt pass a smog sniffer test.
Ok, so how would I know if its tuned or not?
Since it is only in cylinder 1 and 4, it could be something specific for those two cylinders. It might be clogged injectors. I would say check the plugs as well but they are a pain in the ass to check on a boxer engine compared to an I-4 engine.
