Have you checked compression on non firing cylinders? Likely has blown head gasket between these two cylinders if located side by side.

Engine runs ruff


you may have a valve or valves leaking which will cause it to run rough, have a leak down test done or a compression test

95 volvo 940 (non turbo) wont start:(


At night, with the lights off and standing in some dark area, open the hood and look for fireworks.
I chased a similar problem, also degrading over days in a lousy Saturn the same year as your car, that was a miserable piece of junk only months after buying it new. That particular problem, only one of dozens occurring before it self-destructed at 57,000 miles (dropped a rod bearing cap), was 'only' the spark plug wires that were leaking like crazy, arcing to every piece of metal possible. The car was 3 years old at the time.
I STILL hate that car and GM! They deserve bad luck . . .
