Went to start out after car warmed up, throttle began to go up and down. Car had very little power (like limp mode)
Plugged in my code reader & received these codes
1) P0120 throttle/pedal position sensor switch A circuit malfunction
2) P0221 throttle/pedal position sensor/switch B circuit range/performance problem

After letting car cool for a couple hours the power has come back, but the codes are still there!
This is my wife's car and i don't want it to leave her stranded.

I have been told a few different problems that it could be but I dont want to just throw multiple new parts at it when it could just be pedal sensor or throttle body or engine harness.

Any body run in to this?

did this end up being the throttle body? my car is doing the exact same thing

It ended up being the harness that goes to the throttle body.
