Yeah, I had my truck completely die on me due to an ignition module.......always a good thing to replace while you have it all apart.

Good job on the repairs! :drinking:

Well that took care of the idle and die situation.. runs smooth now untill you really get on it and then it starts missing a little... just feels like it doesn't have 100% power . I just checked the timing and put it on 0.. Put the fuel pres on 42 without vac,, drops to 38 with. The only issues I havent dealt with yet is that the previous owner put an A/F ratio meter in the cab and spliced it inline with the O2 sensor wiring harness( just picked up the new harness and will install tonight) and the wire is now broken on the harness. the one in the cab works and is showing rich most of the time. But it's questionable as to whether the ecm is getting the signal. I also checked the passenger side pushrods and was unsure how to adjust them correctly ( think I know now, gonna do it with it running.) they are clicking a little but not like crazy or anything.. would either of those cause my miss at WOT? I will run a datamaster on the way home and then try and figure out how to post it..can someone help me with that?
