I have an '89 too.
Do you have the stock carb and ignition? The stock carb is a POS!! Stock ignition is just as bad. Makes a big difference as to where we start to getting the engine to run better.
So; what are we working with?

Would bad sending unit gasket on the gastank cause rough idle?
I got slightly rough idle in my 89 wrangler 4.2. I do know the gas tank seal is bad. I am wondering if that is causing a vacuum leak and resulting in rough idle?
