High temps, horrible gas mileage and peformance, rotten egg smell, I would agree, cat on its way out/plugged. But, there are 2 cats on this truck, at least, my 99 adn 2000 have 2 cats...

If you have a way of measuring HIGH temps, measure the difference between the 2 cats, they get EXTREMELY hot nayway, but, the plugged one should show cooler temps DOWNSTREAM, due to lack of exhuast...
