You need to have car scanned for fault codes, go to AutoZone they do it for free. They will tell you the reason for the reduced engine light and the check engine light.

You have some kind of ECU problem. You will need to hook to the diagnostic port to find the problem. Your vehicle has gone into limp mode. This enables the vehicle to run, but at a diminished level until you can seek help for the problem. Do not continue to drive it this way as you may cause damage to the engine depending on the nature of the problem.

i had a similar issue today, but it was after an accident. I hit a dog, a very large dog. Anyway, the battery ran out from my having my hazards on, and then the key got stuck in the vehicle. No power, no turning over etc. The tow truck guy boosted the battery, and then pushed in (with a long screwdriver) the switch that is under the steering wheel. He wiggled the sterering wheel a bit as well, and voila, out came the key. this is a feature that GM put in their vehicles. Very common problem, and once power to vehicle it spits out the key.

hi, those sound like throttle actuator codes. the throttle body on your vehicle should be an electronically controlled unit without wires to control actual acceration an deceleration. now, there is also an electronic switch called a potentiometer on the gas pedal that transmits signal to the throttle body to tell it what to do. most of the time, the throttle body is what goes bad here. you should also check the wiring to the unit for bad connection by wiggling the wire connector and seeing if the reduced engine power light comes on. if this happens, you will likely have to replace the wiring pigtail and the throttle body. but, in some cases, the gas pedal switch goes bad, and likely what is not allowing the transmission to shift out of park, the pcm may lock out the solenoid controlling the shifter. but, don't just run with that answer, it maybe completely wrong. i have seen more throttle bodies and wiring harnesses go bad than gas pedal switches in those vehicles. but you might want to have a shop diagnose further, it may even be two unrelated problems, or in the powertrain computer itself.
