My 2001 Protege started running rough about a week ago. I thought it was the transmission but tonight the Check engine light came on. I read the computer and it had the P0303 # 3 cylinder misfire.
I am planning a tune up, Plugs and wires, new PCV valve. I had the Pre- Cat replaced a year ago. Has anyone on here had the same issue? If so what did you do to resolve it?
Any help will be appreciated guys.........
