    Faulty Throttle Position Sensor

    Well i think my TPS has gone pop on me. My symptoms are :

    Bucking and jerking of the car
    Idle surging
    Sudden stalling of the car engine
    Hesitation while the driver of the car is trying to accelerate

    Has anyone had this problem before?
    Do i need a complete throttle body or can i just buy the TPS?
    Could it be something else?

    Any feedback appreciated guys.

    I'm thinking mine might be going or on its way out as when i let off the throttle on the motor way there's a massive jerk rather than the power coming off slowly. How much are these parts?

    If you plug it into op-com it gives a read out of where it thinks the throttle pedal is, think it gives a figure to 1dp. It also gives the doubled figure (to check itself).

    Dont know if doing that would help?

    If it was faulty does it always throw up a code?
