I had reported the following problems earlier:
- Instantaneous engine shutdown ( or momentary studdering) while travelling at speeds greater than 35 mph.
- Tachometer drops to zero even though the engine is still running.
- The "Trac Off" light comes on
- Check Engine light sometimes illuminates. If the engine shuts down, it has never failed to restart immediately.
The dealer performed a fix outlined in GM Tech Service Bulletin # #
000604049 but the problem persists and in fact it has occurred 4 times in the past week.Anyone else had this problem?
