What does it cost to a misfire code P0301?

Call somebody else cause the oil light reset got nothing to do with a P0301 code!!!... Don't guess at this misfire code... Have it tested to find out what is wrong before installing any parts... Anything less is simply guessing!!!!!!

Replace the plugs as there is high resistance and burning through of the porcelain to ground in the plug hole. I would assume he put out the CEL (Check engine light) not the maintenance light. If he didn't do anything besides that it will come back on.
