this will be the second time this device is replaced. I will most likely be replaceing again in the near future, every 5-6 thousand miles, is there an aftermarket part for the DPFE Sensor?. The problem is the car in low rpm's going up hills and minor accelerating, or just toeing the gas in 3rd and 4th gears. The car would slightly vibrate. I was just wondering if there was an aftermarket device to replace this item so it does not happen agian?
