You know Gilly, I think those techs at the dealership would have replaced my wife if they thought it would fix the car and get it out of their shop. At one point it was pulling up enough codes to deplete thier parts department of M119 fuel management components.
I suggested, through the Service Advisor, that they replace the sensor without qualification as to which one. The tech recommended that the dealer keep the car overnight to test cold start in the AM. Reported "PERFECT" and I picked up the car.
Do you think that the above was just a "bandaid" and that the problem will reappear?
