SOURCE: 92 Jeep Wrangler MAP sensor bad?
This may not be your MAP but your Catlettic Converter. I also own a 92 Wrangler and had some of the same issues. My issue was actually a couple of things but they all came from a crack in my exhaust headder.
You may want to check your exhaust headder for cracks. If there is even a small one, (which are VERY common w/ YJ's) than your O2 sensor is thinking that the engine is running too lean. Therefor telling the fuel pump and injectors to dump more fuel into the engine. Well, truth is your not running too lean, in fact, you begin running too ritch.
The unburned fuel that is now comming out through your exhaust collects on the porslen screen inside your catalettic converter where it burns off, causing the screen to melt together. Resulting in a clogged cat.
The only way to fix this is to replace the ehaust headder (welding the crack will not work) and replacing the cat. This would explane your loss in gas mileage and power, due to over back pressure. The ticking sounds like the back pressure working on your valves.
Hopefully I'm wrong and this is not your issue because it is a very expencive repare. You're looking at around 350.00 to 500.00 just for a good headder and atleast 250.00 for the cat. However, an easy way to test this is to take a flash light and have a good look at your headder anywhere there are joints where pipes come together. Look for black, ashy spots above and around the joint. If you see this anywhere then I hate to tell you but this mite just be your problem.

Should be on the bellhousing on the drivers side just where you need rubber arms to reach it.Should have no continuity between b&c terminals (check with ohmeter) Harness plug is usually on the drivers side between the master cyl and the back of the engine (unless someone moved it)

If the spare has been off the tail gate,make sure the valve stem is at the 9:00 position . Fixed my "tire sensor bad/missing" in my 04 Liberty
