Ok why when u knew they were 02 codes did u spend all that money on that extra unessasary crap I.e. plugs seafoam. Shoulda just replaced ur 02s and called it a day

The best way to fix a problem is buy and install the part named in the code.

I had just bought the truck so I was going to do the plugs and seafoam anyway. I changed a rear 02 and still have the 02 codes. I pulled the convertors and could see right through them, no clogging. Would a vacuum leak cause the 0137 and 0157?

I have read that the earlier V8s were bad about intake leaks. It makes sense that it runs worse when cold and low RPMs. I guess it is possible to give those codes for that... at least that what the Autozone computer says. I'll check later with some starter fluid or carb spray or something.
