After weeks of trying to diagnose a running issue, nothing I have done so far has helped. Actually I feel I've made the issue worse. The car ran "ok" before I messed with it, but not 100%. It would pop on the engine light for a minute or two then go out. Codes said something about the DIS and it going lean. Swapped a DIS, checked IC piping, checked visible vacuum lines for leaks, swapped cam sensor, swapped crank sensor, and swapped coil pack. Still no dice. Replaced the IAC since the center wall was cracked.
Next thing I will try is replacing the spark plugs and wires. They were an issue before... Other than that, I'm not sure what else I can do other than sell the car.
Thanks.
