Got the dreaded 300 and 303 error codes on the way home tonight. Hopefully it is a plug or a coil... Got a set of plugs and a set of coils ordered from Smart Madness so we shall see what happens. Only 136K miles


It is running rough but seems to be able to keep up to speed pretty good so I don't think it lost a cylinder. smooths out at higher RPMs
