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 loosing 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
