Had this 94 eclipse 1.8 for a while and decided to fix the codes it had. Oki replaced the Maf sensor as well as the distributor and set it in time. Now the car starts up and when it idles low it just dies. I’m just stumped. The only things this car has given me is problems. But I just don’t want to get rid of it either. Any help?
 
Too little information to go on. Could be incorrect a/f ratio issue. Could be weak spark. Vacuum leak(s). Hard to point you in a resolution direction without more info.

At this point I'd advise you to check for vacuum leaks. Spray some brake cleaner or starting fluid around the intake and vacuum lines to see if the engine responds. If it does, find and fix the vacuum leak.

Also consider testing the plug wires for proper resistance and grounding/arcing issues. Change if you find a problem.

Also check the condition and gap on the plugs and address/replace if needed.
