Having trouble with it cutting out at low speed e.g around 20mph on light throttle.

Diagnostics indicated the TPS was faulty so I renewed it. It runs better but still cuts out.

Measure the voltage feed and one side is 3.0v and the other is 5.0v with the negative pin in the centre.
Is this correct? I would have expected 5.0v each side and the pot act as a voltage divider.

TIA
