Ok on the ground wire I do believe I understand now. So how do I run an extra ground wire from underneath the control module to my battery? Do I take a spade eye connector and take one of the screws out then put the eyelet underneath the screw and put it all back together then? Sorry if I sound stupid here but trying to visualize here how to hook it up inside my cap on the control module.
Eric

eric,
that's the type info we need to know up front...

confirm:
you have tried 3 different dist on this motor and the mis-fire remained the same....
(that's a strong indicator that the fault source is external,,not in the dist at all)

edit:
doesn't have to be #12 wire,,,I suggested it because it is easy to work with for good crimp terminals connects...
(got some scrap #14 or #16 laying around and some red terminals go ahead and use it)
it's the quality of the physical connect points that counts and most wires available anymore are less strands per size

Actually I have owned a couple of Sun 1115's, the earlier models that were real time patterns rather than electronic sample rate machines, that accompanied with a wide band setup is all thats needed. As far as the dyno goes I worked on two different ones, both in ground Claytons also from a time gone by The later had flywheels to simulate road load and the first was just a load and go machine. Neither were all wheel drive as most of todays but most muscle cars don't have front wheel drive. I'm sure they were both donated to some school and replaced with a detail station LOL

eric,
one step one test at a time...

hook up the ground batt to the shell first and drive it...

leave the module alone for now...

re: second/third set of eyes...
it is just too easy for anyone to not see something immediately obvious to someone else causing a fault or could be made better is why I recommended it...
ex:
you described the harness plug in connect as "flimsy",,,can be a simple as just improve/better secure that to cure the miss...
that kind of judgement call we can't make over the net and so so darn often it is a simple to fix problem source!!!
(that doesn't need 20 tests to sort out the source)

Ok Red I will do what you said. I am not driving my truck the next couple of days but will be getting it out Wednesday evening cause I have to drop it off cause I am getting a new set of rear end gears put it. My other ones has seen better days. I will pick up some 12 gauge wire and hook it up.
Thanks Eric
