Hello, my name is***** you for allowing me to assist you! Is it a misfire type shake or a driveline shake? Has the check engine light been coming on while driving?

Customer: replied 1 year ago.
The shake is almost as if the Jeep is in to low of a speed to be in that gear. pushing the accelerator to the floor stops the shaking or sometimes just lifting up on the gas peddle and not giving it as much gas will stop it. it is almost a jerking feeling like I have shifted up to early. Check engine light is on and the gas mileage is below 10 mpg. It is not stuck in 4wd.

Ok i say do that next. Ask the guys at the auto parts store to connect their scan tool and check for any codes. They will do that for free. If there are any, note them and tell me what they are.
