    Help! Jeep gets to operating temp then shuts off (no check engine light)

    So I think I found the culprit! Took the cps off and the wires are cracked and melted. Looks like they were hitting the header. Getting a new one in the morning hopefully to solve the problem!

    Help! Jeep gets to operating temp then shuts off (no check engine light)

    New Jeep owner looking for help. I just got a 97 wrangler 4.0 5 speed. When I got it the intake manifold wasn't seated properly and would go to the rev limiter as soon as you started it.
