1996 Ford F-150 Eddie Bauer 4.9L Poor Idle Quality, Misfire, MIL Lamp on
Posted to Ford Driveability on 5/2/2002 13 Replies

The truck developed a bad miss at idle overnight. It smoothes out at a higher rpm. Idles rough both hot and cold. I am leaning toward fuel injector and will check them with an ohm meter and check fuel pressure tomorrow. I am not that familiar with this vehicle...
