You say you HAD new coil replaced

So the shop you paid put the problem
in your vehicle?

The other parts don't seem related--unless you
have some reason they were changed

Without the vehicle to test & you saying your doing
you own work --we can't help

Aaron, I had the same problem. It is the most expensive part of course the computer. I replaced everything as well till I replaced it. They are remanufactured and have had problems with them as well. I am on my third one now at 200k miles. Oh and by the way it does not show up on the diagnostic check. Good luck

Put a vacuum gauge on it and see if you have a steady reading. You may have a bad cam lobe or partially burned valve which will show up as a quickly fluctuating vacuum reading. Backfiring is generally caused by the above or by the ignition being too far advanced (yours is not adjustable but if you had the distributor out?, you may have put it in one tooth off.)

SOURCE: 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.

SOURCE: 1997 Grand Cherokee 4.0, ignition shuts down

The likely answer to your problem is that you have an intermittent disconnect in the ignition system. If power supply to the ignition system drops out, some fuel still goes through and when power returns it ignites in the exhaust resulting in a backfire. I would look for a bad ignition switch, or other loose connection that could me making/breaking contact intermittently.

Well, some things need to be done systematically. Check for spark to make sure the coils are in fact working. Check for fuel to make sure you don't have a bum fuel pump and/or plugged filter. Ignition coils will get hot. The very fact that it melted may be the sign of a computer issue. Let me know what you find and then we can move forward.

This may be due to a bad coil wire shorting out GM had many problems with these ..There was even a recall for this a long time ago.. The wire would short out on the metal foil on the doghouse and the aluminum a/c line if there was any damage or corrosion to the terminals...A new distributor ...I had an apprentice put one in one time and he thought the rotor was to point to #1 and forgot the dist cap was like a printed circut board and the rotor was no wheres near #1 good luck

First check all wires for any thing loose.
The muffler blowing up leads me to think the engine is so far out of time the PCM cant correct it.

REally you need to get it to a good mechanic.

'95 cavalier backfired blew out muffler? help


when it backfires there is three things that can cause this water or moisture in the distributor cap or a cracked cap, or if it has a coil pack then mositure on the coils or bad spark plug wires. Fuel pump won't cause a backfire except on two stroke engines. and the other things that can cause a back fire is timing chain, or burnt or bent valves or bad compression rings.
