Engine Performance problem
1998 Ford Explorer V8 Four Wheel Drive Automatic 150k miles
Did a full tune up on the customer car two weeks ago. Now, there is a miss fire on cycl 6 consistently, and a shudder in mid range. Torque converter possible, But for the CEL, "P0306" on the miss fire for 6# seems unlikely. Wire, coil packs, plugs, cam sensor, seafoam treatment. Went away with a hard memory clear. No leaks, good fuel pressure at 40psi, compression tested good at 150psi. Just at a lost of words. This weekend i'm going to dig into it for the #6 injector. I think it's the issuess since nothing else would make sense.
have the same problem?
