My Dad and I both had the same problem. All he did was stomp the gas pedal fast and hard and it fixed itself, mine I had to replace the pedal sensor.

The pedal sensor cost about $50.00 and you can do it yourself. You will need to remove the gas pedal (it is only 2 screws) and unplug the pedal sensor, you will need a star bit with a whole in the center ($2.00 and you can buy the set anywhere) of it. This fix is very easy and it should only take you about 20 minutes to complete.

All the Best

I just had the transmission in my 2004 trailblazer


There is a harness in the engine compartment that has grounded out or shorted. The message 'reduced power' will flash across your driver information display on your gauge cluster. This is somewhat of a common problem for full size Gm trucks (silverado, tahoe, suburban, etc .) and trailblazer/envoy vehicles.

I have a 04 silverado HD and while driving i loose throttle


replace your fuel filter best way to diagnose this one to start, find a way to monitor your fuel pressure if the filter had no effect, do you have any codes *** up ? and if so what are they, let me know, if not you might have a defective fuel pump, the pressure reading will tell, over 40 psi is good.

2004 chevy silverado


The above descriptions of the connector are very good. I washed the engine compartment yesterday, and immediately started getting the reduced enginer power code on the CIC, not performance. After reading several posts, I checked the connector on my 2003 2500HD, and found that the connector was not seated well and had gotten water in it. I cleared the water and the reconnected. The cables running from the fuse box to the connector are so short, the connector is in a bind and is pulled off-center. That is why the connector wasn't seated properly. The code went away, and the performance returned. By the way, be sure to do this after pulling the negative cable on your battery.
