Howdy guys. My 1988 is back to running rough at times. The only code it pulls is the E042. I plan on installing a new ignition module/coil that I have. Any other suspects to check out for this code/condition?

When I put the computer into diagnostic mode the rough running stops. When I take it back out of dignostic mode it will return to running rough.

I also have some HVAC issues. The air conditioning crapped out yesterday. I get no cool air and do not think the compressor is turning on now. Belts look fine. Before the AC stopped working I had some vibration while on the highway and now I have a tinny sound when running?
