Rough idle during hot start
Ok so today I started my jeep when the engine was already hot (just under 210) and when it turned over it idled REALLY rough, and then after about 30 seconds of that, it idled normal and had a significant increase in power. I then noticed the check engine light. It ran a little above 210 the whole time I was driving, but ran fine. I'm assuming the code is going to be a misfire, but I replaced the spark plugs about two months ago. So if you have any clue what it might be, I'd love to know. Thanks

it should be a cylinder #3 misfire, sounds like heat soak

I've heard of coil packs being the problem, but I haven't encountered that, the gist of the article is insulating the #3 injector to keep the fuel from vaporizing.
