Default Re: Engine miss.............

I'm embarassed to say that when I went to change plugs #6 was loose. I had swaped plugs between cylinders the last time my CEL cam on a year ago and I suppose I didn't tighten it up good. I did a compression test and the funny thing is the #6 was the stongest of the bunch at 170 lbs while all the others came in 160 LBS or higher and this was with the motor cold. I put in Motorcraft plugs and had to close the gap down to 45while the old Autolites were gapped at 60. With the new Motorcraft plugs gapped properly my pinging issue is almost gone now. I had been living with that for the last 7 years and 100K miles. However, I still get what feels like a cold start miss for the first 15 seconds every monring. It has been doing this for a year now but the CEL is off and the compression is good so I might change out the coil and the wires when i get time. I was expecting a head gasket or valve recession so I feel better now.
