Review on ACDelco 15150990 Original Equipment Accelerator by Stephen Doyle

This pedal/accelerator assembly fixed the 'reduced engine power' problem in my 2003 4.2L 4x4 TrailBlazer. If your trailblazer/envoy goes into low engine power on steep hills or quick throttle stops, then this is what you need. Installation is easy, it's 3 screws. Keep your hand on the accelerator and you'll feel it. Disconnect the electrical connector from it first or before removing it from the footwell.
