I have a 2.5L 1995 manual yj and when I let off the gas petal the engine seems to stop for a second and it jerks. I went to test the TPS and the sensor wire reads 5 volts. The sensor wire reads 5 volts when plugged into the tps and when unplugged. The TPS is bad so im going to buy a new one but what issues could cause the sensor wire to read 5 volts. I assume the jerking is because the tps is reading a lot higher than it should, it reads 5 with no throttle then with a tiny bit of throttle it goes to 2 volts. And as you increase throttle it jumps up and down. And when you let go of the throttle it goes from 2v to 5.
