[QUOTE="46stang, post: 11755625, member: 3691"] I would data log TP sensor voltage and the rpm signal. I have seen and experienced both of those things cause my car to buck and jerk. If the TP sensor is bad when it happens you will see the voltage drop down and back up even though your foot is still planted. The screwy thing is the sensor is still reading a voltage so it won't set a code. The only other thing I can think of is to also check all your wires going to the pumps and make sure none of them are shorting out or loose. [/QUOTE]
