The igniter that I'm refering to sits in the distributor - the little 4 prong thingy held in with 2 screws that fires the coil. These are very notorious for causing all sorts of crazy drivability problems. The problem is that it ties into the feedback of the ECM for spark timing and duration as well as injector trigger to ECM, so if it acts up, then it can even cause your ignition timing to shift around and make the injectors cut out. It's just a basic thing you can check before you rip all the hair out of your head. The car I had mentioned before I had worked on had almost everything replaced as far as sensors go. I hope this helps you out a bit - Good luck Rooster!
