1) Fix the wires before you pour a bunch of magic goop in
2) Dont use magic goop.
3) Dont yank wires off of a running HEI ignition That **** is old school pre TBI and pre HEI
A good way to fry your ignition and possibly jolt the crap out of yerself.
4) Dont pour magic goop in your engine. Its all a friggen scam, you might as well use tarot cards and a sacraficial chicken

Lol. I will not mess with the plugs or wires while running. If this new temp sensor and oil change doesnt fix it, I will do the compression test.

Changed oil and temp sensor. Runs beautifully on cold startup. Oil pressure doesnt go below 15psi when warm. Still has a low rpm idle and kinds shakes when at a light or in park. Doesnt stall or come near it though.
