Suggested Repair

Have the diagnostic trouble codes read to identify the failed system, then follow up with those codes for further diagnosis.

Conversation Summary

A 1994 Buick Park Avenue Ultra with a 3.8 supercharged engine starts normally, then the check engine light comes on after about a mile and the engine runs rough. Restarting clears the light temporarily, but the problem returns within a few miles. If left running, it can stall; at idle it runs poorly until the throttle is pressed. The expert advised reading the trouble codes and reporting them for further help.
