hey zookiacs, thought someone migu be able to help on this one. When i have my aircon switched on and the air in recirculate (regardless whether heating or cooling) the idle will fluctuate between 2000 and 2400 rpm. Anyone know what the issue or fix would be?

Hmmm did the watch carby as fan is switched on thing the arm with the two adjusting screws moved, but I could not see well what moved them. Does anyone have any pics that they could point out on what I should be checking, adjusting or (Shep) unplugging?

Thanks

Do any of you guys have a picture that you could show me to indicate the part I need to relieve my carby of?
