89 4cyl 3.2 88hp banger

The car was running fine for 6 months after some gave it to me.. suddenly it gave out .. every time i would try to start the motor it would not start and it felt like it rough starting.. So i figured the distributor cap may need to be changed... I changed dist. cap I labeled everything before taking it out.. So i know for sure all the wiring is correct. Plus i double checked the firing order here on the site.. NOw.. the engine starts but its running really rough... before i start spending i would like to get some ideas of what you may think it is..

the engine starts right away.. it goes to 1200 rpms and than idles out to a little over 1000 rpm but it runs reallly rough

Thats a tough one. I think it's possible that maybe one of the spark plug wires may be the culprit. Since you moved the wires one may now be arcing to another causing a misfire. I'd hate for you to buy new wires though because it could be many things. The only thing I can think of is maybe somebody will let you borrow a spark plug wire so you can try swapping it out one at a time to see if it solves the misfire, otherwise you'd be taking a chance on buying a set and that not fixing it.

Did you also change the rotor?

Pull one wire at a time with insulated pliers and see if the skip changes...... Could be fuel related also.
