Got a strange one. The sled rarely comes down from the high idle/warm up mode. Hangs between 2200 and 2400 rpm. Here is what I can tell you. It has a SLP air flow intake on it, and has not had a problem till this season. I have swaped out the air sensor on the side of the air box as when I was playing with it the rpm's droped down to the normal 1800ish. This did not make a difference. If I move the air box back and forth slightly the rpm's will drop down with the hood open. As soon as I close the hood the rpm's go back up. Once I lift up the hood again the rpm's will drop back down. If it was the intake boots that I have heard are a problem you would think it would not make a difference with the hood up or down and would be consistant all of the time. Any ideas?
