spark plug fouling
So I have had my mustang for about a year now and I gave been having problems with the msd coils the Last guy put on, they go bad one by one and I've been replacing them one by one... anyway last one that went bad I had aboUT 60k miles on the car so I got 8 spark plugs. Put them in everything was fine then another misfire code, so I swapped the could from cyl 2 to cyl 6 and the misfire stayed on cyl 2. Pulled the plug and found it was carbon fouled after 2 weeks. Checked cyl 1 spark plug and that was fine. So I replaced the one plug in cyl 2 and low and behold another misfire code a week later same cylinder 2 new plug now has carbon fouled again. I had one more plug laying around so I threw it in and on the way home from work I get another misfire code on cyl 2. Why is my plug on cylinder 2 keep carbon fouling? Anybody else have constant misfire problems?
