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

:shrug:

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
