The engine has developed a misfire,most likely. Did the check engine light come on or start flashing? If so, find out what codes has set to determine which cylinder is misfiring and then proceed with the repair.
If the car has no Check Engine light, and it operates well at all other speeds, then I have a question to ask.....have you had the vehicle for a while and is this a speed range that you drive at consistently for extended periods of time? I say this because if you drive at consistent speeds for long periods you can actually wear a dead spot in the throttle position sensor (TPS). This will cause a drop-out at the point of the dead spot which feels like a jerking motion.
Check for vacuum leaks on all hoses underhood. Make sure all intake componets are intact and they are tight.
Is the check engine light on? If so, get to an auto parts store, they should pull the codes for free.
Sounds almost like a bad throttle position sensor. The computer uses the TPS to help know when to shift on this car if I remember right, and if the TPS is bad, it can cause that jerking. Along with the car dying when slowing down after driving. But check everything else out first. Including electrical connections.
YOUR MECHANIC WAS WRONG EXHUST SYSTEM PROBLEMS ARE VAREY BAD DOSE YOUR CATALYTIC CONVERTER MAKE A RITTILEING SOUND IF SO ITS NO GOOD AND WILL CLOG THESE VEHICLES NEED TO MAINTAIN BACK PRESSURE IN EXHUSET SYSTEM TO MAKE ENGINE SYSTEMS FUNCITION CORRECTLY YOU SHOULD HAVE CHECKED BY ANOTHER MECHANIC BEFORE ITS TO LATE AFTER 2 YEARS THERE IS MORE WRONG WITH IT GOOD LUCK
Have you changed the trasmission fluid and filter in your jeep lately, if not do so and that just might stop the jerking in your jeep, and if that does not do the trick you will need to have your trasmission checked out by a trasmission shop.
Is the check engine light on? If it is, take it to an autoparts store and have them use a scan tool to retrieve any fault codes stored in the car's computer. Most stores provide this as a free service. The code(s) will help narrow down the problem. Hope this helped.
