E36 320i Stalls while idling

[NVADER30 0]

This has probably been covered before but I'm fairly limited in the time I have to get this posted. This morning when I stopped at a set of lights the car idled fine at 700rpm for about 15 seconds before suddenly dropping revs to almost zero. The revs then surged back up to 1.5k before dropping down to around 700 again.

It continued to do this every time I stopped unless the road was sloped.

Gearbox is a JATCO auto btw.

Anyone heard of this before? The car had the normal e36 idle problem but it has never done this before...

Mine does the smae thing. Obviously a common E36 problem!

Can anyone else help out?

I had this with my 328i. Take it to a dealer or decent independent, such as Botany Motor Worx (with a scanner). The issue with my 328i ended up being a faulty cam position sensor - this was picked up by the scanner.

After a lot of searching around it seems like the best place to start is the ICV (Idle Control Valve) so I'll take that out and clean it this weekend and let people know how it goes.

Found a good guide as to how to get to the ICV on an M50 Engine here

I had a similar problem before, cleaning ICV was no help and eventually changed crank sensor.

Found a crack in the pipe between the Mass Air Flow Sensor and the manifold. Will order a replacement from BMW shortly but I would say that'll be problem solved

Cheers for the help all
