When my '02 9-5 Aero acted like that (check engine light on, died at stop signs), it was a faulty throttle body controller. I don't know about the cruise control -- I was in town and didn't try to engage it -- but probably the car disables it in its "limp home" mode. I took it to the dealer and described the symptoms, and the service manager immediately diagnosed the controller. (I said "Whatzzat?" He popped the hood and pointed it out to me. I said, "Damn, that's $500." He went in and looked up the parts & labor cost and it was $506.34. *sigh*) He stuck a Tech2 on it and confirmed his diagnosis, so it's easy to verify. BTW I'm at 77k miles right now. I should probably familiarize myself with DI cassette symptoms and replacement procedure. Any pointers? Gary
