OK! So the bowden cable referred to is the one connected to the accelerator pedal.

I found 07.1-2006 Testing Electronic Idle Speed Control in the FSM.

I also see listed 07-2053 as listed for Preceding work: Testing and Adjusting Idle Speed (07-2053).

There is enough slack in the cable so the spring stop is fully seated. I don't want to pull in the slack in the gas (diesel) pedal to raise the idle.

I see that there is a screw with a lock nut located to the side of the EDS on the injector pump.

I think I should solve the "rich" condition first before adjusting the idle.
