BMW 323 Injection

Hi Sandy

One of the features of the L-Jetronic EFIs is that if the rpm are higher 
than 1500 when the trottle is closed (idle) then the fuel is cut off.

This presents a problem if the idle is set too high. If the idle is set too 
high, the engine will rev up to about 1500, cut out, and then come back on 
at about 500-600 rpm.  This will keep up all day until the trottle is 
opened slightly.  


This is especially annoying when trying to get started with a manual 
transmission.  If you engage the clutch as the fuel is cut out, the engine 
dies.

...this is only one of many possibilities or course....but it's worth a try 

Werner

This is a change of pace for me, I just got a 1980 BMW 323i Alpina with a 
great 2.3L 6 cylinder! One problem with it however, is that the idle is 
unstable. It will 'motor boat' up and down, usually stalling out. Other 
times it is stable. I haven't as yet found out much about the system, I 
think it is a bosch j-tronic, it is all mechanical, fuel distributer, etc. 
Any ideas where to start looking?
