With my 1984 240s and older, I noticed and expected that blip up in idle speed when the compressor kicked in.

With my 1988 240 no such deal. The car has a tach, so I can see. I believe that there is a difference in the ECU controls. When the compressor kicks in, the ECU adds a little more air which just compensates for the compressor drag, so the idle stays pretty constant.

Regards,

Bob
