It should go from no code to code 11 and back to no code.

no error codes buy doing this.

So this is what I've done. So far I've changed, igniter, throttle body, every vacuum pipe, bled the cooling system, drained the cooling system and refilled, reset TPS, replaced the TPS and it still hunts!

When you plug the AAV port in the TB the hunting stops.

When you unplug the TPS the hunting stops.

I'm just not convinced that the AAV is stuck open as both throttle bodies worked fine and so did both TPS before removal/fitting so I just can't buy that both TB & TPS have gone bad when they worked only a few weeks ago.

next port of call? radiator?
