Hdi high idle

[DeeTurbo]

My old 306 hdi the tick over idle was running lumpy. So I check the tsp throttle position sensor tapping the side of the round part that moves around. I could hear the spring inside rattle meaning the spring had weaken.

I put another on and it was fine and the spring never rattled inside either.

Sorry to jack the thread.

Are these a hard thing to swap mine has a lumpy/bouncing idol.

Do a injector leak off test as it might be a dodgy injector and it's easy to do to confirm.
