Driveline, Engine & DME Tuning
I have BMW e46 328i 1999y.
In cold weather. When I start engine, I get problem with RPM. (http://www.youtube.com/watch?v=p8T4zz-DgIQ).
RPM is jumping from 400 to 1200.
Sometimes go to 0 ;( and after start again get a 1200.
When engine overcomes 80°, engine work normal 700RPM
