Problem when air con is on

[vyseriesII]

Hey all,

Recently noticed when driving with the air con on that the engine revs, when off the accelerator is pulsing like (rev up slightly the drop. surge like) So it sounds like im tapping the accelerator sharlply every second or so. Only does it when air con is on.

Anyone ever experience anything like this and maybe have an idea what it is?

Cheers

Is it when you turn it on or constant?

Sounds like your compressor clutch is slipping, probably should have your a/c system checked out by hooking up some pressure gauges and seeing what that pressures are doing at idle
