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

    the reduce engine power prompt is on and the check engine light is on what could this mean

    I have the same problem on a 2003 Z71 Tahoe.  The truck only has 45000 miles.  I plan on taking it to the dealership to get it checked out.  It was running fine until today when it started to shake after I started the car and then would not accelerate beyond 30 mph.

Might help, disconnect negative terminal from battery for 10 minutes, if the compute is getting weird readings this will reset it and maybe help.

2003silverado reduced engine power comes on . no power at all ,cant go over 30mph.i have replaced throttle body, and accelerator peddle sensor ,(no cure) what could it be ?any help is appreciated. thanks


Neither the Throttle Body or the APP (Gas Pedel -that never fails)
was the problem

Who diagnosed & replaced all that?

Do you have cylinder misfires (bad coils)?

What codes were there when whatever happened
first started?

My 2003 chevy tahoe will not accelerate pass 30mph what could be the problem?


Your problem could be in the Transmission, but most likely it is caused by a sensor / electric part called an Accellerator-Pedal-Position-Sensor (APP-Sensor. If it is the APP Sensor, then you should be getting a signal in the information center saying "reduced power" or a Check-Engine Light.

Engine light flashing cant go pass 30mph, also car shaking.. 05 sts Cadillac


It sounds to me that you have an extreme engine misfire and the engine control computer has gone into "reduced power mode" (The reason for which can only be determined by proper diagnosis).

If your check engine light is blinking, it is the automotive equivalent of posting in bold, underlined, all caps....

it is SCREAMING at you to get your engine control system checked out because you are in the process of DESTROYING SOME VERY HIGH-DOLLAR PARTS OF YOUR CAR!!! (If you have not already done that.)

Sorry I yelled, But I needed to make the point that the light has apparently been unable to make. Get it checked out and fixed ASAP!
