Ignition Contol Problem

My93SC

I have a 93 sc and it doesnt like to idle. Occasionaly will sputter thoughout the rpm range, otherwise runs fine. I think it is the control module but im not sure is this a common problem?
 
stumble

1. Could be a vacuum leak.
2. Could be the DIS module.
3. Could be a dirty air/fuel filter.
4. Could be a dirty MAF.

No easy answer, start to check things one at a time
 
I havent had alot of time to work on the thing, but by mistake I left the maf unplugged and the car idles fine. Anyone have idea as to why.
