2.5L Rough idle

my 1997 wrangler se (automatic) today just started running very rough at a stop light, then as i was going under 30 to go park it would sputter and not let me accelerate ver much. After that i go to drive home and it does the same thing while i was going 45 mph. Then i get home to my apt. and as soon as i stop the rpms drop all the way until the engine was shaking violently so i shut it off. While looking under the engine i saw coolant spewed on the top of the fan shroud. The only thing done to this jeep is no ac and catback ehaust. Where should i even start looking for the problem at?

here is a video i just got of my jeep dying, maybe its the 02 sensors? its not trowing a check engine light at all?

I also noticed the rpms never stay in the same spot if this also helps

Welcome to JF.

When is the last time you did a tune-up?

Thanks! I actually just got it about a month ago and am not sure when the last tune up was
I had planned on doing plugs, wires, cap, and rotor as soon as i get a chance. Should I look into getting authing else for it when i do that?

First I would resolve the failed radiator hose/hoses, if it even was a hose and not a hole in the radiator itself.
That coolant spraying all over could have caused all the other problems.

Look at the back/bottom of your water pump for leakage. It will drip out if the water pump is going bad. It's not that hard to replace. Then I would do a tune up and clean your throttle body and IAC.

The hose by the cap if overflow, I wouldn't expect it to be very high pressure (could be wrong). How do your operating temperatures look? Are you running hot? How do your coolant and engine oil look? Any fluids dripping from anywhere except for up front?
