    If the P0351 is a permanent code, it will eventually clear after driving the car for a while. As long as the code is not an active, pending, or current code, you probably fixed the problem already. Drive the car for a week or two and then check for codes again.

    Welcome to PriusChat!!
    How many miles on this gen3?

    Do you have coolant in the radiator overflow tank?

    Does the engine 'rattle'' for a few seconds when started from cold?

    Wondering if it could also be a bad head gasket. Did the misfiring plug look any cleaner than the other three?

    FYI: you're moderated until you've posted 5 times.
