Have you checked the linkage to make sure it didn't get bent or have something stuck in there keeping it from returning to the correct possition. It has changed for a reason so I would want to find out why before I started to make any adjustments to anything.

i found the throttle shaft on injection pump was gummed up,i had to lubricate and cycle it a few times to free it up.its been fine since.

some injection pumps have their own oil resrvior,i dont know if this is the case with yours.if it is the case,its could be low or need changing.
