Think I found my misfire ?
Finally got back to the car after the holidays. It has a very consistent misfire on just the passenger side. I can hear the injectors and valve train working . Injectors ohms ok. It seemed to run a few minutes before starting to miss, getting progressively worse ? With a bright flash light. I saw faint exhaust smoke from around number 7 plug and or exhaust manifold. Could be ? loose plug not grounding out, exhaust leak throwing off o2 sensor open loop , or a head gasket. I'm going to check the plugs next opportunity. 92 Lt1. 45,000 miles.

I have found that the rear exhaust manifold pipes (cylinders #7 and #8) consistently get loose over time. Need a tightening every once in a while.
