Filled it up. Did the calculations. Getting 14.7 mpg with 3" lift, 33" tires, front and rear Aussie lockers. Millage is still down since doing headers, exhaust, bored TB, and cylinder head work. Better than last check at 13.9 mpg. I guess the computer is still learning the new set up after reset. May be a few more tanks and I will get back into the 15-16 range. If not, I did not buy it for the mpgs so **** it!!!!!!!

wifey left the headlights on for 8 hours... so i had to go give her a jump at work... turns out the xj is not the easiest vehicle to jump start... she would turn over but wouldn't crank.. pressed the gas and she cranked up.. but as soon as i let off the gas to get out and remove the cables she would die... every single time.. wouldn't stay started without gas pedal...
so i two footed her over to the parts house.. replaced the battery.. shoved a little taller battery than the stock one in the box.. more cca.. better warranty.. ect.. fits great..
now she fires right up! these xj's must require a certain ammount of voltage from the battery to stay running... that old one must have been complete toast.. oh well... fixed now!

They do. Also, the alternator will try to pour its entire life into charging the battery. What happens is that the alternator literally drags the engine to a stop. If that ever happens again just keep the engine at 2500 RPM for about 5 minutes and you're good to go. All you needed to do was charge the battery.
