How in the world do you solve this crappy common issue? I was driving to pick up my mtz's in ohio. I stopped at a light off the ramp and the jeep wouldn't go and accelerate normally and I had to pull over for a second. It felt like the tranny was slipping or something. I arrived at my destination and got the tires but when i fired it up, it ran very rough and i knew it was the misfire in cyl 3. I had this happen twice before after a long trip. So i'm sitting there for 30 minutes waiting for the motor to cool down and finally it runs normally and I go home. I have the worthless heat shield around the injector but that's not doing anything. i don't want to pay the dealer to do the diagnosis computer crap that was recommended cuz it's not really guaranteed to fix it. What can I do about this to get me some reliable long distance trouble-free trips?? this misfire is so common that Jeep should've FIXED IT.
