We have in our workshop an 84 318i with a stalling issue, and it's got us stumped for now.
The BMW was brought into us by another workshop that could not fix the problem, so let's see if I can test your brains for a hint as you guys seem to know BMW's left, right and center
Problem: Stalls when engine starts to warm.
Known issue: All Injectors are pulsed full power when stalling occurs, causing engine to flood itself.
What's been done: The last workshop has changed the ECU to a second hand one, changed the TPS and Air Flow Meter.
What we know: The CTS does not cut out (which can caused to computer to put full power pulses to the injectors. Our signals are all being received at the ECU correctly. Engine main relay has been checked, all seems good.
After it has stalled, disconnect one or two injectors to easy the flooding, and she'll start back up and run until the problem comes back. What I also know is that it can be a random occurrence, ie, I've had it running for 5 minutes and it stalls, or 30 mins. What I also know is that if you give it a good boot full of revs, this can also cause the problem to arise.
Wrap ya heads around that, and see what you think, any and all help would be fantastic
