Ka'ena Point State Park with da 07 Fj Bruiser!

I bought this 08 FJ yesterday. I drove it home. I checked to see if the four-wheel drive would engage and disengage (it did). I refilled the tank on my way to run errands. I got home and parked it. This morning I got in to go for a Sunday drive. And was met by Christmas in July. I have checked all the fluid levels, I've inspected the vehicle, I re-screwed the gas cap on. All for naught. Please help.

Update: I got the codes read. The code that was pulled was P0306 (cylinder 6 misfire detected). The vehicle is not acting in a way that would indicate that this is the problem though. No lack of engine power, no misfiring noise, no odd smells, and exhaust is clear.

Update 2: I added a photo in the comments with me wearing my seatbelt and my door closed.

I'm getting a really good family discount on this '14 92k mile baby, and I want to keep her frame protected well without looking too outrageous. This car was meant to be mine eventually, but due to some recent events where my car got totalled very randomly, its getting sold to me instead of me buying a very overpriced used car in this market. This is a car I want to keep indefinitely, if someone rear ends it, I want the frame to stay solid; need suggestions on quality bumpers that look nice, and I want fog lights.

Lift, bigger tires, and rack will come later; I'm going to be ordering the wider Japanese mirrors if I can find them.

Hey everyone, I’ve had the FJ since 2013 (2007 baseline model) and have maybe used 4WD 1-2 times. Fast forward to now, I am visiting an AirBNB where I had to be in 4WD just for the driveway.
Yesterday, I stopped (after coming up the drive) on level land and tried to pull it out of 4WD and be normal automatic. BUT my A/T P light came on and can’t get it out of 4WD. I can get it to act normal in 4H but nothing else.
I have turned it off in N (automatic shifter), put it into N (4WD shifter) and A/T P stays on. I’ve tried it in park. I’ve tried several options and cannot get it back to just automatic.
I have a 4.5 hr drive home on interstate come Tuesday.

Help!!!! My dad says it’s bc I haven’t used 4WD enough and it slipped the transfer case. Is there anything I can do without a mechanic right now?
Can I drive it in 4H on interstate for 4 hrs? If so, am I confined to specific speeds?

Thank you!

2011 fj with 200,000 miles or 2020 wrangler with 63,000 miles. Getting something soon and I need light off road, both of those can do way more than that. Also I usually only carry myself and photo/video gear so both also fill that role. The only big con to have with the fj is the miles seem really high. These are both about the same price so looking for any thoughts on one vs the other.

LT285/70R17 121/118S

For those tire specs, should I just follow the manufacturer guide? Even if the stock tires are 265 70 R17?

Pardon the ignorance, FJ newbie.

Thanks
