I did try to reduce the idle earlier this afternoon by turning back the torx screw where the throdle body is. Dont know if this had anything to do with it, it was idling at 975 my other rig idles at about 7/ 750 they are both six spd

CAN ANYONE HELP?

The Check engine light is on also

 

[AggieJustin]

P0523 - Oil Pressure Sending Unit Voltage too high

P0121 - APPS signal voltage too low

P1693 - Code set in companion module (always show up whenever you get another code)



The P0121 will trigger the Check Engine light. Looks like your APPS might be flaking out.

What do I need to do to repair this?

If you can, I'd reset the throttle stop you screwed with. Aparrently your truck doesn't like it. It's probably sending the wrong signal all over the system.
