Hi Everyone,
I have 98, 5.0 Explorer that is misfiring/not firing on bank 1 only. It was running rough so I hooked up my timing light and every cylinder in bank 1 misses firing about every 5-10 revolutions. I changed plugs, wires, MAF (it needed it) and intake gaskets. It won't pass emissions and was throwing a CEL for too rich, too lean bank 1 but I haven't see it since replacing the intake gaskets. I pulled plugs on bank 1 and they where pretty fouled. The missing gets worse when reving up the engine. This seems to be an ignition problem, but I don't know much about computer controlled engines, because it just plain misses firing. Any thoughts?
Thanks!
