funny smell at start up... Ok evrytime i start my car it has a funny smell to it, and after my LS6 manifold install im using way more gas than before...Could i be running too rich or lean or whatever? and how would i go about correcting this problem.
Look at your LT (long term) fuel trims for both banks, they should read close to 0%, which is ideal. Safe bet is to check them in an open loop, which is when you start your car from a cold start. If either or both of your cylinder banks are reading +8% or more, you are running rich. this would be caused by something screwed up during your intake install, i.e. a vacuum leak or an incorrectly installed injectors.

during the log the short terms kept jumping from like 4% to around O% and after it was 100% full i went to see the graph it said those 14's butidk guess ill see whats up with the injectors. I know all the hoses are hooked up right.

I'd say you are running rich. You should re-check that vacuum line that goes back behind the intake, apparently it has a tendency to leak, which could cause your problem. Did you install anything else new?
