gas mileage

i have a 2.2 and best i could remember it was getting around 28 now i have a 2.0 and its getting 22 ive checked some things anyone else know its sucking gas?

check your vacumme line on your intake and also something I've found common when trying to find a factory gas tank, there are two spots that are a cetch all and cause it to rust through, I know I've looked at a lot of tanks when trying to replace mine and still had to settle with one that leaks a little but I got it fixed with a little JB Weld
