I know jeeps arent made to accelerate fast but. I was wondering if its normal not to beable to get above 2600 rpm with pedal to the floor. My jeep has the 2.5L automatic and has a 4inch lift and 18 inch tires. If its not normal what would cause this. I was thinkin maybe bad cat. Because i noticed the other day my feet were gettin warm and felt the floor and it was pretty warm.
