Re: Another Cylinder 1 misfire in 24v,new plug and coil! new issue!
OK, replaced 4 of the 6 plugs I could readily reach, then replaced the elbow that goes to the PCV valve, and the problem went away for 5 mins. The cylinder 1 misfire code seems to be gone, but the car still has the same symptoms, but the code for the evap system says large leak (It read that before as well). I could not get the pcv valve off the rear cylinder bank, I don't know what I'm doing wrong, or if that is the only problem left. The old plugs were a mix of motorcraft and bosch, now they have autolite platinums. I also took the rubber portion of the intake off, and there was oil in the hose, and oil surrounding the butterfly for the intake. It seems to be coming from the vent hose for the front bank of cylinders. All help is appreciated.
