Throttle Position Sensor (TPS)
The TPS is a potentiometer that monitors the throttle butterfly angle; over time, the internal resistive track develops dead spots or 'noise.' This causes the ECU to receive erratic input, leading to rapid, unintended fluctuations in fuel injection timing that manifest as jerky acceleration or hesitations during throttle transition.

V-Belt (Ultramatic Drive Belt)
Mechanical jerking is frequently caused by a glazed or unevenly worn drive belt. When the belt has 'flat spots' from previous slippage or heat cycles, it fails to transition smoothly across the primary and secondary sheaves, resulting in a rhythmic slipping and gripping sensation (judder) during acceleration.

Fuel Injector Assembly
Partial obstruction of the injector nozzle disrupts the spray pattern and atomization of the fuel. Under load, this causes localized lean-misfire conditions where the engine intermittently loses power and then recovers, creating a perceived 'jerkiness' as the combustion cycle stabilizes and fails cyclically.
