Cruise control

[kspharris]

Hey all. My 91 2.0l n/t auto cruise control is not working. The switch indicator turns orange when turned on and when I push the button the green light on the dash comes on but it doesn't hold any speed. The only vacuum line I see is connected. My throttle cable is loose and I did tighten it but it didn't help. I had to loosen it back up after a couple days of driving because it was sticking and holding the throttle at about 1400. I just got my logger going again and it shows 86% at the floor. Now if I press super hard on the tip top of the pedal I can get it to 91%. Is there a problem with my cable system? Is that affecting my cruise control? Where should I start to fix my cruise? Thanks everyone.

Lost my CC when the auto to manual conversion was done by previous owner... is this issue happening on the summit swap or the eclipse pictured?

the motor in the unit is probably shot.

The cruise has a small vacuum pump mounted just below the control valve. You will see a small vacuum line running between them. When I get to work ill see if I can pull up a wiring pin out so you can check if the pump is working.
