So...I have P 0300, 0301 and 0302.

So far I have;

Changed spark plugs, reset
Changed coil packs, reset

Now, the jeep still drives like absolute dog ****, and still, to this day since I have owned it, when I take my foot off the gas, it revs from 800 rpm - 1100 rpm with no foot on the gas. WTF is going on with this jeep. Fresh Oil change, regular spark plug changes, i maintain it well, but it is doing me a big favor lately and causing a lot of issues making me want this new vehicle badly.

Just a shot in the dark...mine ran a little rough last fall and I ended up doing a thorough throttle body clean, removed the IAC and cleaned well, change the TPS sensor and that made it run much better. You could try that also. My IAC was COVERED in carbon build up...surprised it even ran lol

Also being those specific misfire codes, check the ignition coil connections, and perhaps clean the injectors if you haven't already.
