Probably a vacume leak or tps sensor faulty. Check the fault code first or go to a workshop to get it checked.

Unplug the tps connector and driver if the rpm behave normally. It's ok if cel lights up.

Mine is the Same problem end up I change and calibrate the a new tps.

Clarify what valve sensor before making the correct decision to change.
What is the Fault code number? 14? Idle Air Control Valve?
