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.

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 !!!
