Hi and welcome to 2CarPros.

Given the reputation for the motors Dodge uses in those and the mileage I would suggest you start out with a compression test to see if the motor is just worn out.

Here is a guide on how to run the test:

I would also plug in a scanner and see if you have any trouble codes.

Let me know what you find out.

Hi,

Here is a guide that we need to start looking at in order to start narrowing this down. However, do you have a check engine light? If so, we need to get the codes before we go much further. If you don't have the ability to pull codes, you can go to most any parts store and they will get them for you free of charge.

Lastly, let me know if you have the ability to monitor live data with a scan tool. Clearly if you can't pull codes, then you can't monitor data but I need to ask because that is most likely going to be necessary.

Thanks
