1995 E320 ASR PROBLEM! What do these codes mean?

[BigRed0803]

Car has the occasional ASR light popping on: When this happens car goes into LIMP mode, I can pull over and restart the car and everything is fine, problem is beginning to happen alittle more frequently.

Pulled these codes today on:

PIN 8
-8- Idle speed control (ISC) system at upper or lower control stop or CC or EA indicates "limp
home" mode.

PIN 14
-3 Right EA/CC/ISC actuator (left cylinder bank) (M16/1)
-6 Starter lock-out/backup lamp switch
-12 EA/CC/ISC control module voltage supply

From this it seems that my problem is the Idle speed control that Pin 8 registered what part is that exactly? Or I may be wrong what else could it be by these readings?

Thanks
