Just want to update. I changed the fuel filter last night and the jeep seems to be back to normal and actually running much better than previously with improved fuel mileage as well. I changed the last fuel filter in November of 2011. It didn't quite last two years or 15,000 to 20,000 miles. With an advance auto parts online discount code I got the filter for $22 and some change. Definitely worth the pain it is to replace!
