I would leave the AFM spring well alone. It is sensitive and factory set.

When I was looking at SD1's 15 years ago, a Rover mechanic told me to 
look for 2 things that would indicate trouble:-
1. black goo in the rocker covers
2. evidence of disturbance of the AFM cover.

I would check the ECU, all of the sensors and injectors first.
