Week ending February 8th: 40 hours between work and school.
Slow week at Williams, mostly concentrated on clean up. Installed oxygen sensor on Ford Ranger and cleaned the mass flow sensor at school. I also researched fuel trim and currently trying to get more information so I completely understand fuel trim charts. I have been working with the Motis learning about all its functions. Changed the spark plugs on a Suburban and checked its 02 sensor using the Motis. I learned the graph should go from lean to rich every second and a half. The computer can only tell the injector how much fuel to release but not how much oxygen can be introduced.
Plus you learned about the smoke machine...It was good to have you around.
