97 Plymouth grand voyager check engine light and cruise comes on at he same time . I have no control over the cruise . When starting the speedometer jumps all the way then back sometimes 2-3 times fast . The vehicle works fine up until it gets hot ( normal operating temp) . That's when the lights come on . I'm constantly getting 1 code p0123 . I have changed the ECM , BCM , TCM , tps , cam sensor , crankshift sensor and clock spring . I'm losing my mind . The symptoms present only when engine is warm/ hot . They include high shifting rpm at 3,000 + , bucking when shifting , random stall when gas pedal is released ( not too often ) , sometimes when gas pedal is released at a stop and go intersection the gear would shift to neutral . I tried driving it on gear 3 and it still jerks . Several people have seen of heard of this an everything I changed was what they told me could be the issue . I'm fed up please HELP . Thank you

Before you threw all of those expensive parts at the vehicle, did you attempt tp repair the Throttle Position sensor and associated wiring? That is what the p0123 code indicates. The wiring in these particular vehicles can be problematic and checking all of the wiring associated with the TPS should have been the first thing you did.
