Ok, got to spend the entire day messing with the truck. Had some help
form another ford guy. We found buried under neath everything an
unconnected PCV vacuum line. We got it running good enough to actually
time it to the base 10 degrees and tightened teh dizzy hold down. Plug
wires are driving us crazy. Turns out that we found the O2 sensor out in
the back yard, lol. Not connected either. The iron exhaust manifolds are
not oem to the truck (they were literally broken in half) and so the
down pipes do not fit. Found one that did fit but no O2 sensor bung.
That will be welded in tomorrow. The motor seems to run fairly decently
(well, compared to the last time I was looking at it) except for below
2000 rpm. It acts like there is still a small vacuum leak or something
not connected correctly. And of course the emissions diagram on the hood
is gone, lol. So searching for some diagrams on how all the small 1/8
inch plastic lines are routed and to where they go. Yet, great progress
was made today. New plug wires tomorrow, new coil, some correct hook ups
of the small vac lines and maybe, just maybe.... I did see something
that was really weird though. There is a large hose going over to the
power brake unit. That hose was about an 1/8 inch from the coil wire
rubber cap. As the truck was running spark was jumping from the coil
boot to the rubber hose! So It sounds like the coil wire for sure needs
replacing! Several of the plug wire boots at the plugs are broken off,
most of the plugs are/were fouled. I suspect that is from the O2 either
not being installed or that when it was plugged in the brain box
thinking that it was really lean and cranked up the pulse widths to
richen it up. But the bottom line is that progress was made and more
will be made tomorrow when we figure out where all those small vacuum
lines go...
I want to thank each and evry one of you for the help you sent in the
form of suggestions for things to check and for photos (Terry, thank
your wife for me please), Because it all helped. For those that will be
at speed week, come find my pit and the cold ones are on me.
Again. many thanks from a tired, pooped out, old fart.
mayf
