...i keep on getting the run around by the dealer. they have given these possible scenarios: spark plug misfires and/or when the car is cold or not warmed up i accelerate too fast which causes the computer to be triggered for check engine light. i have around 65,000 miles... - Spark plug misfires usually cause a blinking CEL.
- Accelerating too fast when the engine is cold?? (Total BS- should not cause CEL although not nice to engine in general)
- 65,000 miles is typical for O2 sensor demise.
Please get your diagnostic codes to help diagnose the exact cause. CEL fault codes are described
