I took out the powertrax locker this weekend got my MPG's back up to 19 on the highway!

started up this morning, slight grmble and check engine's on again. thinking it s another random misfire.

I've been very surprised with my mpg here lately. I've always averaged around 17-18 but with the current heat wave its shot up to 20-22. 3.7 seems to hate cooler weather. Drops to 17 in the winter, usually stays around 19 in the summer.

That's with stock tires, flowmaster, and k&n air filter.
