2003 Toyota Tundra Fuel Delivery Reviews

2 reviews
The throttle position sensor was exactly what my car needed to eliminate rough idling and improve throttle response. However, just a few months into using it, the sensor's effectiveness diminished, leading to the same old engine issues. Great at first, but it seems like it doesn’t last.
