- throttle position sensor, ok so i have tried swapping out the sensor and throttle body a few times, it will start up and idle then it will start to jump then die. im running a p28 with a jumper harness, 96-00 intake manifold. please help
...The throttle position sensor plug and the map? plug are the same size. I have on several occasions mixed these up and plugged them into the wrong sensors. Try swapping them and see what happens. Just a thought.
