UNKNOWN. Often when I attempt to accelerate after stopping at a stop sign, the car hesitates, sometimes lunges ahead and then sometimes practically dying before accelerating normally. There have been times when It simply feels like a fuel pump problem and I know that Toyotas with this same Denso fuel pump have had documented problems similar to mine.
