Review on TAMKKEN 234 4407 234 4647 Cadillac Chevrolet by Ron Houston

This is giving me trouble, not working. tested twice. I'm fixing an exhaust leak right now. Hope it works properly after that. I thought something was wrong when I pre-tested it and the heated side showed no conduction. Does NOT work, fails the California smog test. I need to return for a loan, I already ordered an overpayment. Today. My return period has expired. BUT AFTER ALL MY TESTS IT DIDN'T WORK. It must be returned to the seller. I now have one that worked the moment I installed it. WHAT NOW?
