Problem with headers
I just put new flow daddy headers on my XJ and when I go to start the jeep up the rpm shoot way up and stay there. If anyone has an idea of what may be wrong that would be great. Thanks

Sounds like a vaccum leak. Doubt it really has anything to do with the headers. Something something got knocked loose or not reconencted during the installation. Check all wiring and Vaccum lines got connected correctly.
