Hello,

One of the common reasons for an engine to go into low power or limp mode is a dirty throttle actuator. Over time the throttle actuator can have dirt and debris built up inside. Which can cause it to send incorrect data to the ECM and that could trigger the limp mode.

Many times, cleaning out the throttle bore can improve the drivability.
Here is a helpful guide on how to clean the throttle body:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
