97 F150 Misfre ???
I am trying to diagnose a misfire problem on my 97 f150. It had bad coils and I replaced those and while doing that I got new plugs and wires too. Now my problem is still around, however its only cylinders 4 and 8. Before it would be anyones guess to which cylinder would be the problem. I ran injector cleaner through it and no change. Any thoughts??
