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?
