Spraying antifreeze all over engine and hood
My guess would be the fan is flinging it around, so radiator, hose or water pump.
Make sure your radiator is full and start your engine and look for leaks... If you don't see any wait for it to warm up and check again..

How to fix hard start and stalling
If your fuel system is ok(which it sounds like you've checked) go to the distributer cap and rotor,these often get hairline cracks which are not apparent by looking at them, but are cheap to replace. Also while in there make sure everything else looks clean and situated correctly. Then change your spark plugs and if they are not newer,better ones, your spark plug wires too, this often has a profound effect on starting and running smooth all by itself. Use good quality parts (No Champion plugs for example,have run into to many that fail new or shortly afterwards) and change your air filter while your under the hood. You can also use seafoam (slowly added to hose for intake while manually raising the rpms,and the other half of the bottle added to fuel tank) to clean the intake system.If you do this,do it BEFORE you change the plugs as it often fouls them,and is perfect to do before you change them out, Drive a few miles after using the seafoam as well,then change out the plugs and wires etc..

Shifter will not engage 4 wheel drive.
Check to make sure it is connected at the transfer case. The shifter bushings become worn and break and allows the linkage to fall off the lever arm.

Witch fuse should be pulled on 1999 jeep to stop horn from blowing
Your owners manual will show you exactly where it is...However it is easy to disconnect the horn...You desperately need a horn for safety reasons to avoid a crash...Especially if your state has a safety inspection requirement...Your fuse panel should also have the fuses numbered and a sticker inside the fuse box cover stating which fuse goes to horn....Also you can wear safety glasses and disconnect the battery to avoid air bag explosion..Remove steering wheel center cover where the horn is pressed...,You will see a small wire attached to the cover and to the prong inside steering wheel...It could be loose or disconnected.....If not just disconnect the wire and black tape the terminal end ..Then the horn is disconnected...

What controls the idle mixture on a 1999 Jeep Cherokee Sport
hot or cold engine? (EFI controls it all , but)
a cold engine is , MAP and ECT , and RPM , iAT set, by PCM tables.
Inputs >>>. ECU tables >>>> math >>> injection rates.
hot is the same but the engine EFI enters Closed loop fuel controls
the scan tool shows "closed loop status "true"
so the 02 sensors pulls the mixture to STOICH, 14.7:1 AFR.
AFR means air fuel ratio, or mix, in bar stool lingo, (ok)
what is the real question or issue, or just shopping for facts.
both are welcome for sure.
if really curious read the books by :
Greg Banish books , both are GEMS ! (i have them all, and his win big time.)

Brake booster
With the engine off, depress the brake pedal about 6 times, all the way up and down. While holding the hard pedal down, start the engine, and if the booster is working properly, the pedal will fade down a little bit.

Is transmission cooler factory installed?
If it has one, most likely. it should be very obvious if it is not, such as aftermarket brackets and fittings. If there is not an external trans cooler installed, they run the tranny fluid through the radiator (the trans fluid is hotter than the engine coolant).

99 jeep cherokee problem w/ heat
It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).
