Idle Issue

[907DAVE]

I have had a recent problem with my idle speed.

Idles fine normally and when I let it sit and idle for awhile it will roll up to a fast idle (normal). The problem I have is when I press the brake the idle will drop a few hundred RPM (from 1100 to +/- 950), then run rough and not completely return to base idle( I think it is set at 750). It WILL not return to base idle until I drop it into gear, or switch programs. Sometimes it will do this after a drive and I throw it into park, idle speed will jump up and run rough.

It only seems to do this in a certain program and not in the rest, I have compared programs to see if I could find the issue, but no luck.

Any thoughts?
