1993 Jeep Wrangler diagnostic question

The jeep is making a loud popping sound similar to a backfire but more like popcorn popping just really loud. I'm not able to drive it as it doesn't want to go...have to give it lots of fuel in order to make it go. I've changed the spark plugs, checked transmission fluids, oil levels and all other tune up type systems. Looking for suggestions on what it could be and what to check next...

You have either water in the fuel, or you have a plugged catalytic convertor

1993 jeep Wrangler 2.5l runs hot, backfires and dies

the overheating could be causing the backfires as the engine gets too hot
over heating can be due to thermostat being stuck in closed position.
cooler fan not running, or blockage of air getting through the radiator. not enough coolant water in the system, or some other blockage in the cooling system. also using the wrong fuel such as race fuels can cause engines to overheat and or not run smoothly.
I hope this helps.

1989 jeep wrangler starts jumping and backfiring

Start with the basics...meaning check the spark plug wires and spark plugs. While under the hood, inspect all hoses for a vacuum leak(s). Then turn the ignition key on-off-on-off- on...leave in the on position and write down the number of flashes the check engine light indicates....2 flashes = #2....pause.....3 flashes = #3.
Let start from here. Are you able to perform engine repairs or diagnostics???
