Jerry in post 8 gives the most common solution.

Ok so let me get this strait, sorry if I come off clueless but...well I kinda am. Haha. I just zip tie that piece of 8 dollar shield ignition cable around the injector and that fixes my issue? I’m going to post a pic and maybe you can verify my thoughts..

I can't say it will fix your issue only that it is the most common solution to a heatsoak misfiring #3.

Ok cool so do I just zip tie it around where I have it circled on the picture?

Thanks a ton. I’m not new to the Jeep world but I am new to working on my own vehicle so I’m trying to learn.

Please note, Codaman's issue was different than yours. He was experiencing multiple misfires. The TSB only addresses #3 heat soak. Also some on here has replaced the heat sheild blanket that lays on the manifold.

Ok great. Yea I think we had the same codes: P0303. I hope this works.

That TSB fixed my 03 cylinder misfire. This is the part that the TSB specifies and where I got mine from. You just need a small zip-tie to hold it on. https://www.amazon.com/gp/product/B007O3QHDK/?tag=wranglerorg-20

Thanks Jerry. I was not looking forward to replacing the injectors and am glad I came across this thread. I have new plugs and a coil rail so now maybe this will solve my issues with the misfiring in cylinder 3.

Keep in mind you can always troubleshoot injectors by moving them around and seeing if the problem follows a particular injector or if nothing changes indicating it's not an injector problem.
