SOURCE: the check engine light illuminates,

HI...
THis problem is caused for
Lost of correlation between ACELERATOR PEDAL POSITION
AND THROTTLE ACTUATOR MOTOR.
Because your car has no acelerator cable.
The morer probable is the Trhottle actuator motor come damaged. 90%. 10% the accelerator pedal position.
If you turn of the car it will work OK> for a few time.
But the Service engine soon. will stay on.
Yuo can go to at ANy ADVANCE AUTOPART, AUTOZONE or NAPA AUTOPART. They make a diagnostic free.
If not. I recomend get the car scanned for see exactly why the light come on. and make the right repair procedure.

OK>> I hope this help on your question...

Thank you for use fixya.

SOURCE: 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.

SOURCE: parking brake pedal goes to floor

The disc brake pads are NOT used for the parking brake. The parking brake uses mini-drum type shoes inside the rear disc rotor.

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.

2005 suburban stabilatrac disabled


The Reduce Engine Power problem on my 03 Suburban went away when I had to replace the fuel mixing sensor. I damaged the sensor by topping off with E85 (ethanol) by mistake late at night. The vehicle just would not turn on in the morning. The vehicle had to be towed to the dealer. I was in Carlsbad NM about 800 miles from home. I had no choice but to pay $1,100 to get it fixed. At the same time the Reduce Engine Power problem went away. And thanks to God it has not come back for nine 9 months now.

Low engine power displays and in fact the vehicle barely moves


Could be the fuel pump in the Gas tank. Mine crapped out and caused the car to have reduced power for awhile before it quit all together.

Display reads "Engine Power Reduced" and sometimes won't accelerate beyond idle. Other times it accelerates normally. We have not yet noticed a pattern.
