Just wonder if the E34 (M20B25 engine) air-cond idle controlled by the idling valve or there is a screw to adjust?
My problem is when air cond is on at standstill position, the rpm idle between 500-600 (this has caused the engine rev up & down) , when air cond is off, it idle between 700 - 800 (smooth).
Hence, decided to tune the rpm higher. Now, air cond is on, it idle between 700 - 800 (smooth) but when air cond is off, rpm shot up to 900 - 1000/1100 (engine sounds very fast).
Anyone has the same problem? How can I solve the problem?
