Hello. I drive about 2 miles and I go to turn around after and when I go to reverse my car died and I had to turn the key and start the engine again and I go back home and on the way it dies again while driving also i felt a kickback while driving 45 mph if you have any suggestions I would love your advice this is 2001 Jeep Wrangler 4.0. it was a coil pack so all 6. and 6 spark plugs. Only way it would start before was if i held the gas hard otherwise it would just die
