Message:
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

I would start with the basics in this order:

replace #8 spark plug
replace #8 spark plug wire
replace distributor cap
swap #8 injector with another one

Hey Will,

I know what is wrong w/ yur truck.
Almost certain it's a bent valve in # 8 cyl. more than likely the intake valve. sometimes if u don't let it warm up long enough before u jump on the throttle it'l colapse a lifter and bend an intake valve.by the description of yur syptoms this is what has happened to u. there is a very easy and inexpensive way to find ou if u have a valve that is no longer seating , make the dealer do a compresion test on #8 cyl.and see if it is within acceptable range, my guess is that it is not ad the low compresion is causing the missfiring in that cyl.

If a valve was bent wouldn't it run bad or misfire across all RPM's, not just high RPMS/WOT?
