I've had an overfueling problem on my 1987 930 turbo for the last 6 months - Metering head, warm up reg have been replaced countless times and we're still no closer to finding out why it's overfueling on idle and lift off (on gear changes).

There does seem something odd with the auxillary air supply from the right hand side of the intercooler. Basically there doesn't seem to be any air flow from this side at all. You can cut the air supply off from that side (expecting the engine to stall) and it does nothing ?

Anyone got any ideas - or point me to somewhere else ?

Any help appreciated !

Check for intake leaks, cracked injector blocks?

Also make sure that the air meter door moves freely.

If it is sticking it could be holding the metering valve open more than is needed, especially during idle after open throttle and other throttle closing transitions.
