Consumer Description

At 80000miles I noticed misfires and replaced original spark plugs per spec At 107578, misfires occurred, when I pulled plugs pos 1 was completely worn out, as well as pos 4.Codes were seen P0304 and P0301. Car ran well after replacement. I have been troubled by loss of coolant lately and could find no leaks. Also temp gauge in dash “wanders” Being retired I can’t afford to go to dealership. I believe spark plugs should not wear out after approx 25000 miles No overheating of engine has occurred . I drive about 12000/yr. Car is available to be seen. Dealer has not seen car Concerned problem could cause engine failure. Thank you
