2001 Ford F-150 XL 4.6L Misfire
Posted to Ford Driveability on 7/11/2003 7 Replies

I have two cylinders misfireing. I've tested the plugs and they are working. I've swapped the injectors around from cylinder 5 to 7 and there is no difference in cylinder 7. Still misfires. What should the compression be in this engine? My readings are 100 psi...
