E30 idling problem
 

Hi all,

New to this forum. Need some advice on my E30 idling problem. When at P/N with a/c off it will idle at 1.25rpm. When at P/N with a/c on, it will go down slightly to 1rpm. When I change the gear to D or R, it will go even lower to 1 or 0.8 depending on whether a/c off or on respectively. Any advice on what to check?

Btw, my E30 is L-jet 320i 1987.

Thanks in advance.

It's normal. Dont worry about it.
