I had a similar problem with my M50 throttle sticking, turns out my butterfly plate shaft was seized up and there was dirt and crap in the return spring. I had to jimmy up a secondary return spring for a while but after cleaning up the TB and return spring and lubing them a bit it works fine now.

May also be worth noting that my linkage from the throttle cable plate to the TB shaft is also pretty loose and should be replaced some day.

What's the difference between a BMW and a porcupine?
