Car will start & run good, but sometimes will not start. Wait until next day & will
Start again. I believe it hase a coil or module overheating but others have said
It could be a sensor. ( under dash )

Replace ignitor and coil:

If CEL ever stays on, when the ignition switch is turned to ON, perform the K-Test on the ECM.

Good luck trying to find a new igniter at an autowrecker!
I got quoted $130 for a new one from my local autoparts store!
