I have a 2010 Sahara with about 130k. This started a few months ago. When I start it up and press on the gas, I’ll go for a few feet before it loses power. When I press down on the gas, i get mostly air and the Jeep bucks like it’s trying to go. It will begin to accelerate for a second or 2 and then lose power. This game usually last about 30 seconds before the ABS, traction control and ESP/BAS come on at the same time and it magically corrects itself.
