Hey everyone, this is my first post on here so hopefully I got this in the right spot. My girlfriend has a 2003 2.4 Wrangler SE. From what I read online it seems to be the TJ but maybe someone could explain this to me since I'm very new to the Jeep world.
The car has been relatively well kept. I noticed when she is on the highway the change between gears is not smooth, it starts shaking as if it was going to stall when being rev'd around 2k rpm. Then her transmission shifts down one and revs around 4k, all while pressing on the gas. There have been several occasions where her car will stall when she comes to a stop. Once it stalls the car will not turn on for a few minutes although you can hear the engine turning.
I have done a lot of research online and from my personal car knowledge it seems to be a fuel problem or transmission problem. I was hoping someone who knows more about jeep could help inform me of what this is. She brought her car to the shop twice and they said nothing was wrong...No codes are tripped when hooked up to a scan gauge.
