I had a p0302 and the plug was done. I replaced the plug and get p0300. I replaced all plugs, they were toast. I also replaced wireset, it was oem and two of the wires resistance was marginal. I have check each coil pack, primary and secondary side, and all readings are within specs. Still throws P0300 consistantly.
