Re: 08 Patriot computer problem?
Not familiar with your jeep, but if you really will need a new PCM (powertrain control module), there are places where they sell refurbished ones, or you can send yours in for repair. When you give the required info to them, then they can pre-program the PCM for you.
But do you know which code(s) it was giving? Sometimes they are a bit too easy to tell you to buy some new part, while at the end it was something different.
