hey, i am still haveing a huge problem with gas mileage on my 98 2.7. last time i checked, the thing was getting around 10-12 mpg. this is horrible! im running 32 11.50s with a 3in cornfed lift. any ideas on this one? i had my exaust re welded on that that gave me a little better mileage but not much. This thing is really raping me on gas and its a 4cyl!! i did replace the oxygen sensors a while ago so they are new. i have noticed a huge buildup of black carbon stuff in the tail pipe. it is so bad that it is starting to get on the outside of the pipe, weird....
