It sounds like the oxygen sensor in the exhaust you would be better of getting it plugged in to diagnostics

1st thing to do is hook up a diagnostic monitor and see what the O2 sensors are doing and at the same time run a self test on the emission system for any trouble codes ( the dealer has this sophisticated test equip), if there is any kind of problem the check engine light should be on, this trucks electronic control system is very sensitive to any kind of malfunction. What is the fuel mileage? what engine do you have? are the tires properly inflated? low tire press eats gas. Let me know and we will try and sort this out.

My 1996 Jeep Cherokee 4L 6CYL heater stops blowing and defroster starts blowing when the engine is under load. Let off the gas and the heater starts blowing again. I think it miught be a vacuum leak... Any...

Vacuum leaks can be identified by spraying small amounts of carburetor cleaner around the vacuum lines/hoses & connections. Any area that sucks in the carb cleaner will cause the engine to idle slower for a few seconds. Spray sparingly & allow to dissipate/evaporate between spraying to prevent any possible fire danger. The problem you are describing could also be the vacuum resivoir having a crack in it, it usuall stores enough vacuum to allow acceleration without affecting the heater controls as yours are being affected. this is usually a cannister or a black plastic mounted ball shaped device that has vacuum line(s) leading to them located on the fenderwells. good luck

Jeep dies when you let of gas

Check/replace the Idle Air Control Valve, located on the intake manifold. It is likely sticking or otherwise not operating correctly.

Also, check for vacuum leaks.

96 Jeep cherokee ran out of gas, re-fuel, won't start. No spark.

You may have to prime the fuel pump. Or replace the fuel pump if that does not work. Why do you let it run out of gas? This is definately not good for an injected motor. It will continue to cause more and more problems. Fuel injectors should never run dry.

Well it seems that a leak has shorted out some of the circuits. This may be able to be resolved if nothing has suffered permanent damage, but that will have to be diagnosed by a professional with access to the Jeep. For now, disconnect the battery keep the Jeep in a dry place so the moisture can dissipate.  Use a hair drier or fan to help speed up the drying process.  While this is going on, you will have to search for the source of the leak and get it fixed, the most common area for leaks is around the windshield.  If no permanent damage has been caused, and the moisture is all dried up then you may be ok.
