I have an 86' Syncro, and when I turn on the AC initially every= thing is fine. It works great.  After a period of driving when I come d= own to idle it sticks around 2500 rpm. A few times it has stuck there and I = waited about 30 seconds and all of a sudden it just dropped down to normal. = It also drops back to normal when I shut off the AC.  This leads me to = believe a switch or valve is sticking. Does anyone know what valve controls = the Idle when the AC is on, and whether or not this could be my problem? Thanks for advanced
