My throttle had been sticking at about 1500 rpm until i press the gas pedal sharply, then it goes back down to normal idle rpms. I recently replaced the throttle cable and made it run directly from the firewall to the carb, instead of in a loop as it was before, and the problem was much worse, until I adjusted the part where the cable cover mounts on the carb in order to make the curves less drastic. It seems to be a bit better now, but still sticks sometimes until I blip the throttle. If I open the throttle manually on the carb, it goes back to idle no problem.. so its not the springs, or the carb in any way. The spring on the gas pedal feels a bit weak, but I'm not sure if that could make this happen. I am thinking that the cable must be sticking inside the cable cover somehow, but I have lubricated it with LDL dry lube spray very well. Should I use a different lube? Has anyone else had this problem? PS. I have an auto trans, and the cable from the trans to the carb is engaged anytime the throttle is opened. I know it should slide and only engage when the throttle is wide open, but I did not have a problem with it before. Could the tension from this cable help the throttle close?
