Default Little help please "codes"

The codes I pulled were

P0430 Catalyst System Low Efficiency Bank 2
P0441 Evaporative Emission Control System Incorrect Purge Flow
P1626 Theft Deterrent Fuel Enable Signal Not Received

My B1-S2 02 sensor was in the 150s, The other 3 were fine. Idle was around 1250 and should be around 800, The MAF was reading 0.0 the whole time, IAC Position was at 0 but when I hit the throttle alittle bit it would read. We also put a smoke machine to it and found a leak around the Throttlebody.. At first we thought it was the gasket but pumping more smoke it looks like the smoke is comming out of the spring on the TB.. So im tihnking a bushing inside the TB? I also have a small rip in my intake elbow from my nitrous lines being pressed down from the hood.

Ok it's been a while but I had the PO430 code long time ago, turned out to be my driver side rear 02 sensor was all. If not the driver side then passenger but think that was the order.

for codes this site was good for OBD-II: http://www.projecttransam.com/projec...lue=Info-Codes
