Skip codes PO205 and PO305 S80 2002

posted by  someone claiming to be MittenHed for Volvo Doug on  Wed Sep 30 07:01 CST 2009 [RELATED]

The car is a T6 with about 60k miles. There is an intermittent skip that shows codes PO305 and PO205. They translate to injector circuit open #5 cylinder and cylinder 5 misfire detected. The wiring and the injectors have been ohmed and all read the same. Is there some connector that gets weird? Or is this a sign of a dying injector or computer?

    Most common reason for a misfire is a bad coil. Without positive response from coil, ECM might not ground injector. I'd swap coil #5 with another and see if the problem migrates to that cylinder. In that case, you got yourself a bad coil.
