I'm a bit puzzled hear and you may have 2 problems. P2135 is a throttle position sensor fault and is caused by when both sensors don't add up. So not to have the Toyota problem where cars would suddenly accelerate GM found it smart ( And it is ) to have 2 sensors one positive and one negative. The ECM continuously monitors both of these and adds their outputs together it expects a 0 answer +/- 3. If it gets a reading outside these parameters it will set a code P2135 meaning TPS is out of specs and will put engine in reduced power mode so it doesn't crazily accelerate like a Toyota. Now if you turn off and restart your car on the same day more than 3 times to get around the reduced power on the fourth occasion the code comes up you will not get a reduced engine power and may get a high revving engine to rev limit. Price you pay for ignoring the warning signs of your ECM. Now once you go pass the fourth cycle the car will not let you go fast no matter how you try, not shifting into second gear is it's only hope to try and save you from getting killed. So my guess is change your throttle body and have the learn procedure done and clear all codes and you should be good.
