Question about 1991 Buick Riviera
Throttle position sensor may need to be replaced or checked. Any codes? Check engine light on? As the 1-2 shift, the detent aka kick down cable may be out of adjustment.This cable runs from the throttle body into the transmission. It has a button on the cable near the throttle body on cable housing. Push it in and this will loosen the cable. With car off, mash the accelerator all the way down and this should reset it.
