Anyone with Autodata (throttle adjustment)?

[lewisdmz]

I'm still having some issues with jolty throttle when coming on/off the throttle no matter how delicate I am as well as some typical stalling issues when revs are dropping to idle.

After a lot of reading online it seems that this issue could be caused by the throttle plate closing too much (some vehicles require a very slightly open throttle all the time to relieve the icv of all the work).

There is a screw on the throttle body which allows you to adjust the closed position of the butterfly, I was wondering if anyone knew what this should be set at or if there were any servicing guides in autodata?

thanks in advance
