The problem is in the code p2138. This is a problem with the fuel pedal, with the pedal or the wiring causing the issue. The fuel pedal is not linked to the engine with a cable but now has a sensor on the pedal that sends a signal to the engine computer which controls the throttle. The pedal has 2 sensors located inside of it, when the 2 sensors do not agree on the actual position of the pedal it will set this code. The engine goes in to reduce power because the engine computer sees a issue. This stops the car from taking off on you. To fix this problem the wiring near the pedal needs to be checked, also the wiring to the engine computer. If the wiring is good, the fuel pedal needs to be replaced.
Let me know if you have more questions on this issue.
