Run problem...
I've got a 2000 Corvette with a LS1. I put headers on it along with 02 simulators for down stream and up stream into the headers. It seams to be running very rich. Any idea how to correct this problem?? Thanks

Did you put sim's in both places? You need O2 sensors in the upstream spots and a tune since you put headers on

did you put catless headers on? it may or may not be rich, but you are likely just smelling the wonderful fumes of a catless exhaust....LOL
And yea you also likely need a tune... and then get rid of the garbage o2 simulators.
