Either a Fuel Delivery problem or an Air intake problem. Possibly spark. Try this: https://www.youtube.com/watch?v=xQGSkWEC_u4

SOURCE: 99 jeep wrangler 4.0 backfires and hesitates

Fairly common problem. Typical scenario is start vehicle, runs fine for 15 to 30 seconds and begins to backfire when placed under load as customer tries to drive vehicle. Flooring usually makes the problem go away. Usually does not throw a code.

Fix is to replace the upstream 02 sensor.

SOURCE: backfiring and loss of power

'till you do some in depth testing of all systems, I'd place equal weight on every possibility. Make sure you cover the basics like fuel filter etc before getting crazy with it though. Also check cap. rotor, coil and wires. Idle cylinder pressure is different than that encountered when driving. This additional pressure will cause ignition spark to seek a better easier ground,(not the spark plugs where it should be going) causing missing under load.After checking , if you haven't found anything, its time to begin testing fuel pump pressures, modules and controls.
good luck

SOURCE: backfire into intake

I'ts quite possible that your distributor is installed one tooth off and is too far advanced, causing the plug to fire before the intake valves are closed completely. Turn it one tooth counter-clockwise and try it again.

After it warms up when you come to a stop it will die, cuts out and backfires before it restarts


I think you are going to have to pull the engine error codes to start the diagnostics. Do you know the key trick? With the engine off, put in your key and turn it until the dash lights come on, but the engine doesn't come on. Do this three times in a row and leave the key forward the last time. The odometer will now change and either display the error code, or say "Done" if there are none. Once you have the code, google-it and see what you get. You could be looking at an ignition, throttle-body, or injector issue. Hopefully the error code will start you down the right path.

Motor backfires when you slow down to go around when you start to accelerate sometimes it will backfire


Your main problem could be anything from Timimg out by 2mm
problem with hole in exhaust system ,,or a gasket blown on the intake.
To much fuel getting in the engine and as you throttle back the extra fuel in the chambers fire without a spark.. with the heat of pistons
The way to check the exhaust is get someone to listen to the engine in park and you put on a glove and put your hand over the tail pipe and if the engine stops and cannot hear a whistle under the bonnet then the exhaust is ok
Let me know how you get on ASAP Ron

Jeep will start but not idle when it's cold out


You have a cold start injector. It basically primes the fuel into the engine.
It`s like the old type `choke` systems.
Get it checked at an auto electricians.

96 Jeep Cherokee Sport Hard Starting


The Engine coolant temp sensor would ABSOLUTELY cause a hard start, but don't guess get the codes check again at Auto_Zone to make sure. Another cause of that kind of hard start is a dirty throttle body/ intake manifold. Use INTAKE cleaner and a rag clean the intake esp[eciall in the throttle body area. Good Luck

No power to dash or dome light in 2003 jeep tj.


As far as the guage issue it is most likely a problem with the body control module, have a trouble code test run on the BCM to determine the issue, the stalling is caused by the loss of the idle strategy learning when the battery went dead, the best thing to do is the following procedure I use to clear this issue.

Here is the most common cause of surges and stalls (or very low idle) near or at idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
