This has been a real head scratcher. My '94 ES-300's check engine light came on and the engine started cutting out a while back. It would intermittently start and run for anywhere from a few seconds to a few minutes. Diagnostics indicate an ignitor problem. I replaced the ignitor and cleared the codes. The car ran fine for 15 minutes or so. The check engine light came back on, but the car ran fine for a couple of weeks. It started cutting out intermittently again at that point. Diagnostics again show the ignitor. I replaced it a second time and had a similar result.
After talking with a few others and looking at the electrical diagrams, we ended up replacing the ignition switch, clearing the codes, etc. The car again ran fine for a couple of weeks after the check engine light came on.
Has anyone seen anything like this before.
Thanks for any input you may have.
