I have a 97 Taurus with cylinder 1 misfire. My diagnostic equipment seems to indicate excess fuel on bank one. The O2 sensors are working fine. Any ideas? It does it warm or cold.
Thanks!

When I had my Cyl Misfire code come up at about 75,000 miles or so I determined that my original plugs were worn. I replaced them and the wires and after resetting the code the problem was solved.

Plugs and wires have been replaced recently. I know one is fouled but am looking for cause.

Plugs over gapped and fouled number one. Problem solved for now.
