Stepper Motor & Metering pins
Went to do the "nutter" to my 1990 Wrangler 4.2. Will not idle, only runs when above 1500rpm, has a mis or stutter at most any rpm but is much worse at low rpm. Anyway, I decided to remove the stepper motor to see what these metering pins look like. I removed it and no pins. So i get a mirror and light(you cannot see it unless you were a contortionist weighing 75 pounds) to see what was inside where I had just removed the stepper motor.There are three holes aligned vertically. One hole was blocked or what i thought was the back of the "pin". I took a small allen wrench and while looking down the throat of the carb, pushed the pin in from the back. What came into the carb was not a metering pin like in the pictures. What I got was a piece of metal, kinda like the head of a large straight pin, round, and like the body that was once connected broke off.WTF to do now?
