I have a 2007 Chevrolet Silverado and I can start it but it doesn't rev up nor does it have any throttle when I push the gas pedal. On my dash underneath my speedometer it says reduced engine power. I cant figure out whats wrong with it. It started this after taking off from a stop sign. Also my brake lights and tail lights dont work anymore they stopped working before the throttle thing happened. Also when i go to take off from a stop my truck jerks really hard its done that since i bought the truck. Theres 3 problems i dont have the solution for so Can someone please help me. I dont exactly remember how many miles are on it.

I have a 2010 Chevy silverado that when I start truck I put it on reverse and backs up fine, shift to D and no movement rpms move but speedometer barely moved at 4500rpm. Removed fuse#19 and put it on D and moves sluggish for a bit then drives smooth. Transmission rebuilt 2 years ago truck has 129000 miles. Could it be a wiring issue if so what should I look for. Or is it check balls, in valve body, pump, or solenoids , fluid is fine not burnt and it has plenty fluid

I put my truck in gear while the mortar was reved up and it pop and won't move and it clings in rear end
