Have an 89 325i with manual transmission. Replaced all vacuume hoses, tps, afs, fuel regulator, injectors, ecu, temp sensors, o2 sensor, idle control valve, spark plugs, rotor, distributor cap, spark plug wires, valve adjustment, compression tested, timing belts, alternator, etc. Emmisions tested very good BUT off-idle hesitation Problem won't go away. What else could be causing it?

If you add fuel (like spray carb spray while accelerating the engine) does the hesitation go away?
