Driving around town (potholes galore) I note that the reset, usually the current ? screen (the one that is three left button pushes from BIG INST, my preferred usual setting), about 1 time in 5 I noticed the ver .82 screen, and the changes always came at a jarring pothole. I wonder if bouncing around on the dash is actuating the pushbutton switches. The speed and gph readings in the multi variable screens seem stable. With the hard alkaline backup of power, and behavior consistent with stray switch closures, this seems the most likely explanation.

Are most of us with this problem driving on rough roads with shot shocks?
