Ok heres whats going on. Im sure most of us are familiar with the gauge cluster test mode you can do by holding the trip odo button down during start-up. Ok well you know how when you do that it says "Test gauge" and all the needles move and max out for a second and then go back down to where they are supposed to be. Well every single time I start my focus my needles do this, whithout me doing anything, im not doing the test mode or anything, they just do that anytime the car is started, why is it doing this? It also seems like the car doesnt know what its doing initally, kinda like when you clear the ECU by a battery disconnect how it idles really high (2k rpm) for a few minutes and then kinda works stuff out back to normal, and doesn't drive all that great for a few miles. I cant figure out whats going on, its just started doing this in the cold weather about a week ago

i had same problem for a while. if you've got a security alarm water may have leaked into a wire and/or also check the chord/connectors. mine were loose when this happened and i tighten them to bejesus

Maybe your Trip Odometer reset button is stuck/push in.
Have you tried to verify that it's functional by pressing it to see if the trip odometer resets
when the car is running ?

Problem is very simple. Connection is bad or to low voltage from the battery. In case of bad connection or low battery voltage the computer resets itself.

I saw this problem many times on very-very cold nights and mornings. Not a big problem, just disturbing a bit, you can forget it.

so how exactly can I fix it, just replacing the battery is the only way? My alternator is also under-driven

its your connection, clean up the terminals with a brush, baking soda and water, then reatach the cables snugly...seen it a ton of times.

When you accessed the test mode, did you access any of the options or did you access the Test mode then turn you car off ?

I had this problem too and it was driving me nutty. I was in the middle of my sound system install and had a 4 gauge wire connected to batt but not to the amp yet and it was doing the gauge wipe. When i got everything installed it stopped. then when i was installing a second trunk light and started my car with some open 12v wires it did it again. And when my brake light went out it did it too. Seems to happen to me when somthing shorts out or is disconnected. Check your fuses and connecitons if you have aftermarket stuff. Check all your lights and stuff like that.
