Time to pick your brains again... Recently my idle has begun to "hang." Here's the scenario... I pull up to a red light, step on the clutch, pull out of gear, and the RPM's get stuck at 1600 on the way down. It happens maybe every other red light. The only way to bring it back down is to ease off the clutch in gear while on the brake and then release around 1000 RPM. Note that idle is set at 800 RPM. What do you suspect the culprit is??
Thanks!
Bobby
