91 300e with ASR

[944s2c]

I was wondering if anyone out there has a 1991 300e with ASR?If you do, could you do me a favor ? Remove the air cleaner housing(3 nuts).Turn ignition switch to ON.Under the hood,rotate crank that is attached to throttle cable to the full throttle position and observe the arm attached to the throttle plate. DOES IT GO ALLTHE WAY TO THE STOP?The stop and arm are under the air inlet of the throttle body. The arm should move toward the left side of the car when linkage is moved to the full throttle position.Iam asking some one to do this because mine is only going 50% of full throttle.Is this how it is supposed to be?Thanks for your help,Dan
