I'll look into that.
In the never ending quest to solve the problems with my truck, I went to the
dealer today to take a look at it through the eyes of a DRB-III.
Everything seems to be ok, except #8 misfired 15 times in about 2-4 seconds
(At WOT).
What could be causing this? Bad ignition coil? The whole thing still pings
pretty bad at medium/heavy acceleration. Could this all be related?
Thanks
william
