Assuming you have Motronic 1.5, have you checked the idle speed control
valve - this is a rotary valve which controls the idle speed by opening or
closing as neccessary an air channel which bypasses the throttle plate.
These can get affected by oil/carbon from the breather system which causes a
blockage or sticking; maybe heat is making this worse?
Just a thought.
