So, more data today. Compression check came back at 115-120, cold, across the board. Lower than I'd like but I don't think enough to cause the issue I'm having. Being as they are all even, did not do a leak down. It does have 230k on the clock so I know it will need attention sooner than later. For now I think the base engine is ok. Anybody know an actual spec for this, stock? Best info I found was "within 10% and over 100PSI" lol I hooked up a test light and found cylinder #7 is not getting consistent spark, very erratic. Next move is to pull plenum, check injectors, and check distributor and cap.
