My best bet would be to 1, change the fuel filter, 2, change the air filter, 3, clean the throttle body air intake with carb cleaner, 4, add a fuel injector additive to your fuel tank, 5, add an oil cleaner to the engine oil let it run for 20 or so minutes then, 6 drain the oil, 7 remove & replace the oil filter, 8 refill with good quality engine oil all but one liter, 9 add a one liter can of Ametech Restore, 10 change the spark plugs, 11 check the leads, 12 check the dizzy cap and rotor arm for cracks corrosion etc and replace if needed and then 13 drive with as low as revs as possible for the duration on the ametech instructions, all this done at home should cost no more than 150.00 pounds & if it does then you have been ripped off, this is far less than a garage would charge you for a basic service

When was the last time you tuned up your Jeep? Spark plugs, cap and rotor can certainly attribute to if not cause the problem you are describing. Definitely sounds like a fuel problem (too much fuel being dumped in the cylinders.)

I have a 97 jeep cherokee that stalls and backfires and it has backfired to the point where it blew open my muffler. It doesn't backfire all the time, just at times...what can it be?

It's not possible to pinpoint, with just online info, what is causing the backfire, but if it blew your muffler open, the engine is definitely dumping raw fuel into the exhaust. Look into what can cause excessive fuel to be dumped into the exhaust and you may find the cause of your problem.

97 Jeep Grand Cherokee only blows heat and ac out of dashboard

There is a vacuum leak under the hood. If it's a 6 cylinder, look on the drivers side for a vacuum line that runs vertical with a 90 degree angle fitting to the manifold. That one usually comes off. If it is a V8 look on the battery side for a broken or corroded vacuum line.

1997 Jeep Grand Cherokee. Stalls out,engine quits running

since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.

Battery charge spiked up on 1994 jeep grand cherokee ltd.

check the battery cable connections, are they clean and tight? This can cause the charging system to spike and go into the 16-17 volt range, the other thing is a problem with either the alternator or the voltage regulator, a diode that is failing can cause this issue.
