By the time I pulled into the parking lot at work it was barely idling. > > I have reconnected the O2 sensor and will continue to be amazed by the quirks of this system. > > Chuck > '85 Wolfsburg Westy -- 'Roland' > > In a message dated Wed, 7 Mar 2001 7:47:31 AM Eastern Standard Time, Mark Ingalls <ingalls_mark@HOTMAIL.COM> writes: > > << In Closed Loop the FI system constantly corrects the Fuel Injection to > provide the best compromise between power, fuel economy, and emissions. 14.7 > to 1 by mass, not volume. > <snip> > Bosch's closed loop system is a big advancement over carburetors or open > loop FI systems.
