1997 Ford F-150 XL 4.2L MIL Lamp on
Posted to Ford Driveability on 11/23/2013 19 Replies

The sensor comes on very slow, and never goes over .3 of a [...] does not respond to carb clean when trying to force it rich. I suspect a wiring problem, pulled the harness apart and found nothing. Not ready to swap computers just yet. Thanks for the help.
