Finally back in the states, the Army decided my life was not complex enough as it was.
Anyway, I replaced the Crank position sensor and the Speed sensor (both on the Bell housing as suggested by PorcheBMW above. I got real excited because it ran fine, but as usual after 3-5 min. it started missing again.
Then I had to go on another mission so I took it to Midwest BMW in Columbus, OH and dropped it off for 6wks. They checked all the sensors, fuel pressure, airflow sensor, everything they could think of. Their final suggestion was to replace the ECU, (a noid light to the 4,5,&6th injectors showed a weak signal???).
Bought ECU... car ran fine for 3-5 min.; then as you guessed it, she started missing again.
I'm really beside myself... I've put too much into this car, but can't figure it out. Could it be the injectors???
I would really, really appreciate any suggestions.
