OK, here’s one for you. 2002 Buick LeSabre with 3.8 motor.
Intermittently acts as if the Rev limiter is engaged. No power and won’t go over 30 MPH.
Stop the car turn off and restart, All is fine. There are no codes and no warning lights.
Could the TPS cause this issue?
That sounds like the car is going into limp mode. Is the check engine light on when this happens?
