If it helps anyone else, I think the problem was a bad ground between the head and the upper motor mount (torque arm). The error code had started to show up with premium fuel as well. Cleaning the terminals made the "check engine" light go out after 10 minutes of running the car. Dave Wysocki '93 9000 CSE
