Main issues with 2005 Jeep Wrangler Unlimited. Poor gas mileage and rough idle. Took the Jeep to Huntington Beach Chrysler Jeep. Was told the jeep had carbon on two LIFTERS and other issues. Cost around $550.00. I told them to do what ever needed to be done. Picked Jeep up around closing time and still have rough idle. Drove for a couple of days and still very poor gas mileage. 90 mile to a half a tank. It's a 19 gallon tank. Went back to Huntington Beach Chrysler Jeep and was told that nothing more could be done about the rough idle and that these Jeeps get very poor gas mileage anyway. I was too upset to talk and left. What did I pay $535.38 for!
