    On my 99 Subaru which still misfires now I have a emission system failure, I cleared all the tubes and valves connected to the system from the engine side and none of the connections appear to be badly damaged. So wondering what's exactly wrong because there's no code to specify where exactly the trouble originates.
    As always help appearciated.

    Have you tried resetting the ECU?
