Equipped with the Howell EFI kit, the engine ran without any hesitation, allowing the Jeep to idle through most of the trail. On a side note, after hosing out the inside of the Jeep, I let it sit out to dry where it started by itself and almost ran over my dog. As it turned out, I had mounted the relays for the steering column under the dash, upside down. They got water in them, which completed the circuit and caused the starter to engage. Mount the relays for the steering column so they will not get wet!
