Suggested Repair

Have a professional shop diagnose the check engine light with proper equipment before replacing the computer. Parts-store scans are not always reliable.

Conversation Summary

The owner of a 1995 Pontiac Grand Prix 3.1 reports the service engine light comes on, especially when speeding up and then slowing down. An AutoZone scan produced no codes and the tester suggested the computer was bad. The expert advised taking the car to a shop for a proper diagnosis rather than relying on the parts-store result.
