Failed / faulty 78-84 ignition module
Last fall returning from a 928 GTG in Milwaukee, my 79 just felt "off". Holding steady down the highway I could feel / hear a slight miss and WOT after about 4500 and the exhaust tone just sounded funky (this is my car with straight pipes and headers...)
The green wire was old and I had a new one in the tool box so I figured that needed replacement anyway. That fixed 90% of the problem, but the odd exhaust tone above 4500 was still there and just felt sluggish.
With winter looming I parked it for a nicer day.
Yesterday I pulled her out, did my "spring ritual" and once completed dug into this problem Since I have three spare ignition modules I stared with those.
Thankfully the harness is long enough you can do a "temporary" setup just to do a quick test drive.
All three performed the same and fixed the problem.
The point of this thread? Up until now my experience with these units is they either work or they don't and the car doesn't run or hardly at all. I'm not sure most owners of a 78-84 would have picked up on this, the exhaust note was the smoking gun here since I'm very accustomed to how this car sounds when angry.
Does anyone recall who rebuilds these?

Interesting. Glad you were able to pinpoint the problem, especially when part of you was believing it was most likely something else.
Have no idea who rebuilds them, but after reading your post...I believe I should maybe get an extra one.
