Uh, I'd guess it's a '98 Jeep Cherokee Sport.

Didnt see the year in the first post dont be a d@#k. If you want to contribute put somthing usefull into the members thread. don't clutter it up with smart comments.

Now for the problem if it is a heat soak issue there is a shield you can put on but it didn't help with my heat soak. The only fix I have ever found that worked well was a switch wired to my a fan so on short stops I could just turn my fan on and that kept the engine cooler by moving air over the engine

It wasn't in the first post. It's the title of the thread. As for the problem, do hood vents.

You need to learn some humility.

Modsjeep11, the 1999+ 4.0L engines are notorious for heat soak issues that caused vapor lock with injector #3 due to the design of the newer intake. However, the 1998 and older designs are not entirely immune to this issue either. The first cheap fix to try is to wrap heat shielding material, such as DEI heat wrap, around the misfiring injector. If it turns out that heat soak is not the issue then it will be down to a faulty injector or wiring to that injector.
