My 1999 Jeep Wrangler Sport quits momentarily when I hit a bump in the road (paved, not off-road). It starts running again in about a second or two. Computer, maybe?

Change the bulb End see if that works, If not there is probally a short,

1. Engine mount issue: If your car's engine mount is worn or damaged, it can cause the engine to move excessively when you hit bumps or rough roads. This movement can cause the engine to momentarily stall or hesitate.
2. Fuel delivery issue: If there's an issue with fuel delivery, such as a clogged fuel filter or a weak fuel pump, it can cause the engine to momentarily lose power when you hit bumps or rough roads.
3. Electrical issue: There could be an issue with the electrical system, such as a loose or corroded connector, that's causing a momentary loss of power to the engine.

I would start by checking all the fuses and relays under the hood , you can have one or more fuse or relay disconected or loose from the big bump
also go threw chack all electral conections, one or more might have come loose
it would be a good idea to go threw all fuses and conections unplug and plug back in.
Let me know if we need to dig deeper into it but i think you will find a loose conection

sounds like a ball joint

The front chassis susspension rubber bushes are worn and need replacing..

Check the wire that feeds voltage to your ignition system. Check any connectors or plug-ins on that wire. It sounds like you have a bad connection. I've had this happen before, including on my motorcycle! Hope this helps!

hi its probably the fuel cut off switch. in an impact an enerchia switch will cut off the fuel pump. your local dealer will tell you where its fitted and its just a push of the switch and away it will go.

I had the same problem with my 1997 Wrangler. I seem to of solved this by turning the ignition to off then depressing the lock on the immobilizer. Then waited for about 10-15 seconds after the red light on the dash quit blinking fast . Then I hit the unlock on the immobilizer and the Jeep started and ran ok. I guess the immobilizer is the culprit and it doesn't unlock initially

I had a similar problem with my 2000 Jeep TJ and I found the problem in the wiring harness under the hood.several wires were corroded and almost burnt off.If you remove the black tape which keeps the harness bundled together and if you see evidence of "green" type powder or "gook" it's most likely where the wires have faulted.

first, you have to tape any open wires with electrical tape, so they DON"T short anything out again. second, check your gauge fuse.
