I would get it scanned. most auto parts stores will do it for free, autozone does for sure. It sounds like it may be a crank position sensor, but that's just a guess. you should be able to google search how to check the codes without a scanner. I know for most mopars you turn the ignition switch on-off-on-off-on, and then watch either the check engine light or digital odometer. the digital odometer will display all of the codes the computer has stored so you can look them up, if it's the check engine light, it will flash, and you count the flashes, there will be a break between codes. this works for the obd1 models, and should work for obd2 as well.

You should check compression before throwing any more parts at it

Not a bad idea.

It could also be a vacuum leak, EFI engines are better able to compensate for this and can hide the issue better, but it is a possibility. A major leak, like on the line to the brake booster can cause those symptoms, not necessarily a miss, but something similar to it.
