Do you think sensors like coolant temp sensor and camshaft sensor could cause codes to come up saying both banks running rich? I was thinking of replacing the top 2 o2's, but just wanted to rule out all other options first before forking over the money since they aren't really that cheap. There aren't any air leaks that I know of so I don't think that is the problem. (most times wouldn't that mean it was running more lean than anything anyway?)

Anyway, yea I am still moving out that way. The first weekend of March to be exact. I am renting an apartment in Endicott.
