Subject:   AC ON / High idle problem

As i'm stuck in the /%&$%?/!$?&% snow, i could not make it to Everybus, so i'm working...

Rarely that i ask for help but maybe now someone had that problem and can give me an hint, i'm NO AC guru at all.

The van is an 87 with AC

Problem: customer drive the van with AC ON on freeway, get out of freeway, let go of the gas pedal, Idle stays at 2000 RPM, close AC, idle is fine, put back AC, engine rev up to 2000.

So, on Digfan/late Van, i can not trace what control the higher idle when AC is ON, i know that the ISCU (Idle Stabbilizer Control Unit) control the Power stering higher idle but not sure about AC, anyway, i thought i ask before i get into that problem and loose precious time. I didn't take a real look at the schema but will later.

Thanks guys
