Thanks for the reply....In gear at stop without AC 6k, out of gear at stop without AC 9k.....With AC on, in gear at stop 6k, out of gear 7k. What do you think? A little low? and if so how do I adjust the idle. I've never worked on this engine before other than plugs and plug wires plus an AC idler pully but I hate to take it all the way across Tucson just to adjust the idle, also I have noticed that the linkage is quite complicated so maybe it's best left to an expert? Thanks, Desert
