Al,

I had a miss that took me forever to track. A "reputable" "recommended"
SHO place did a 60k for me before I took over all the work. I pulled
the intake again, checked all gaskets, replaced one wire at a time, and
umteen other attempts and parts swaps. I finally pulled the new plugs and
the three  back plugs had double washers on them. Something so basic caused a
hesitation and backfire throught the intake. Hope its something this
simple..
