(reported on)Grand Prix 3.8L V6
- Automatic transmission
- 60,000 miles
My service engine light keeps coming on and off and blinks. I've had it at the deal multiple times and had several diagnostic tests. I have had my catalytic converter replaced twice, 6 O2 sensors replaced; I have had it at the dealer 4 or 5 times with the same answer, O2 sensor. My check engine light is still on and I think it might be related to much bigger problem.. See my other complaint under transmission.

Grand Prix GTP 3.8L V6 Sc
Wasn't sure if the injector was bad or because of the Maf sensor ( showing low input ). swapped the #3 injector with #1 and after running the car, DTC code showed up #1. I knew then that the injector was bad. also had to replace the Coolant Temp sensor. Been a little over a month and today, the car cut off on my Daughter. after checking the Code, it now shows a high input on the MAF sensor. What a Pain !!!
