Since coil packs would only affect individual cylinders,that shouldn't cause it. My "not being there" guess would be the fuel pump or the computer.

I need help diagnosing the problem with my '99 Jeep Grand Cherokee laredo. I drive it for a while, it 'bucks' or jumps (sometimes violently), then sometimes the engine dies. The RPMs go all the way down and I pull over. After about 5 to 20 minutes, it starts back.

At one time, my car went for three or four days without dying or 'jumping' at all.

I am leaning toward a faulty coil pack (ignition coil)....

ANY help would be appreciated!
