I have an 82 GL 4wd wagon, EA81, and the carter carb, the car is idling at about 3200 RPM's consistently. will not go up or down unless in gear and driving. i cannot find any vacuum leaks, i just replaced a couple gaskets in the carb where there was one. i took off the choke thermostat thing on the side of the carb completely and started the car. still no change. I am stuck, please help with any advice you have.
