No parts replaced starting coming up with reduced engine power light with no effect on drivability then all of a sudden. Same light came on and I couldn't accelerate. I'm going to try cleaning the throttle body after that no idea. Please help!

Cleaning the Throttle Body is a good start.
Let me check if there is more information. What model and year is your vehicle? -
Please doble check the code number, there is no P1271 code listed in the factory service manual.
Unfortunately there are many things that can set the "Reduce Engine Power" warning light. I recommend starting by checking for codes and if possible use high octane gas for a couple of weeks. -
