Jeep Error Code - 3 cyclinder misfiring question

Hey guys well I bought a 2001 Jeep cherokee sport with 129k miles on it a couple weeks. Well low and behold it drives fine when I bought it. No leaks, ticks or anything except the typical lower oil pressure but I had two mechanics look at it at a dealership and at a local shop and both say it is fine and good to go and dropping headliner that I took out redid it myself. The last week it has been 100+ degree everyday and I notice my car starting to have rough idle and the engine light came on. Well I looked up the ignition wire heat shield and the debris manifold cover from the recall and TBS reports that could cause that issue. So I ordered them today and the dealership will put on next week on Monday. I am hoping that will solve the issue as I feel it is a heat soaking issue. I am also going to take it to the local mechanic and get a quick tune up just for smoother idle and get the injectors cleaned. I am also putting a die hard battery in it but do you think I should just the gold level, advanced gold, or platinum level? Do you all think this should solve the problem with the misfiring issue?

That sounds like classic signs of heat soak. I had the same issue with mine this summer. Installed the insulation around the number 3 injector and haven't had an issue since.
