Went to start the truck today, and like the title says brake pedal went straight to the floor as I went to press the start button. Let brake pedal back up, press start button, yellow light around button came on, then put foot on brake pedal again, this time brake pedal was again firm and truck started normally. No MIL light. Have had both brake updates done. No further trouble today. Anyone else experienced this?

  Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10. There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.

  passive listening likely misses a lot of useful data for any system probelms (vs bus/communication problems), which are more common. and you would need to poll most everything, because you have no idea what/where the problem happens, and data from just prior to the event is likely more important than what's happening after the event. It would likely be more useful/successful, to be set to look at a specific subsystem, so after some random problem happens, then you attach this device, set to watch/log for that specific problem the next time it happens.
