It is at 6 now, I have tried to set to more advance but the motor runs uncontrollably and heats up. My truck is fairly loud as well to be running at 2,500 rpm at 12 degrees. I will reset to 12 and adjust idle and af once I fix the issue. tried plugging each vacuum port and it didn’t change. I can unhook the throttle cable, with a double and tight return spring on and when I pull back on the throttle get it to idle fine. As soon as I let go it runs back up to 1,400. Could this be a worn throttle plate? The idle screw is all the way out or not touching so it should just die.
