oh lol yeah if its 12 hours it should be good to go just reconnect.. before u disconnect the bat make sure u roll the window down a lil because with the bat disconnected it wont go up and down when you open the door
Well i just put back on the negative this morning and windows close and open slightly like they should, being that i didnt open them before i took the battery out. WHen I get to school I will update on how my gas mileage went, ill try to drive no more than 5 miles overthe speed limit and i just got my filter changed this month, so, update coming soon.
Ok, so let me start by saying that im 19 and its hard driving like my GRANDPA'S grandpa. After plugging my battery back i noticed that when i check my Economy screen on my gps, it read 137 miles until empty (a little more than a half of a tank, just a little). I started off driving slow doing the speed limit being passed by almost everyone. I left the economy screen up and was getting 28 MPG! My MPG went down to 26 after i ran from the police for speeding 
I wish my morning was that interesting but it did go down after accelerating to get on the highway. During all of this tho I forgot i had my heat and heated seats on (its 27 degrees outside) But by time I arrived at school the screen read 25 mpg and 155 miles until empty. Im not sure if it was my driving habit or the battery but ive never got 28 mpg before.
It was nice getting good gas mileage but honestly, its BORING AS HELL!

I did the 12 hour disconnect. We were working on some things and left the battery unplugged over night. The next day, I had to reset all of my radio controls and started watching my MPG (I have a Z so we have the info meter, you would need Navi on a G to get it) and it skyrocketed.
I normally don't drive my car hard unless at an event.
Also keep in mind, I have a Vortech, Split Second, FMU, and 440 injectors, so needless to say, I was thrilled.
