I'm waiting on my new gaskets to get here then I'll check the 2nd cat. Lowest my tank ever gets is to 1/8th of a tank. I'll have to check the plugs again, I'm pretty sure they're in there securely, I've has the boot pop loose before and tend to check anytime I'm under the hood.
I'm starting to wonder if I have a defective upstream O2 and if I should replace booth since I only replaced one of them.
Thanks for the input Gee!
