I've had my Jeep out offroading a bunch, which in itself isn't bad. Its nice to get away from people.

My frustration is that now its winter, I expected an MPG drop. What I DIDN'T expect was the almost 4MPG drop. And I haven't significantly altered my driving habits, other than slowing down a bit when its slick. I understand the fuel formulations change and that warmer air is better. And I didn't add that much weight with my extra winter carry stuff.

During one offroad trip I did have the vacuum line come off the MAP sensor, but when my CEL came on I did the key cycle check for codes, and it showed the MAP, sure enough replaced the line with a new longer (2" longer to allow for movement) hose.

MAYBE, I need to reset the computer. I am going to do an upper grill block fro the winter and see what I can get away with (Jeeps overheat WAYYYY too easy)...
