Have a general question.

My Patrol 2000 DX 3.0L idles smoothly at 750RPM

When I turn the lights on (High Beam with driving lights)
Air Con, cigerette lighter, hazards.......the RPM increase to about 850RPM (Air Con seems to cause the jump)

When I turn off all the accessories, drops back to 750, but when I turn on the Rear Demister the idle RMP jumps up to 1100-1200.

When I engage the clutch and select ANY gear the idle spped drops back to 750.

Can other Patrol users confirm this is normal operation?

In-laws have a 3.6 Petrol Prado and it does not behave this way.

Can I assmue this is standard Deisel behavour?

Thanks

Paul
