Yes (you do have to buy the housing as well, the motor isn't available separately as I incorrectly said earlier. Sorry about that! ).

I had exactly the same symptoms as you have Nathan and I only renewed the motor which cured the fault. So buy the repair kit if you want to but I think you'll be wasting your money. Why not try the motor first and see what happens?

The information I gave you was from MG Rover's technical manual RAVE and it actually applies to the Throttle Position Sensor (1.8 engines only) not the stepper motor! I have informed Rimmer Bros.

Anyway I'll get around to replacing the adhesive gum asap.
That fitting to which the tube is connected should positively connect to the IACV housing with a click. Some up and down movement is normal but it should not be possible to lift out the fitting without depressing the locking collar.
