Lean Code Help my car has LT's 3 inch ORY catless, 02 sims, and new plugs and wires. i've had the headers on for a few months and the car ran fine, then it came time for inspection-i had to reinstall my AIR to get the code not to throw (i have the emission style headers). the car passed, but it did show a problem with an 02 sensor. a few days later, the car throws a lean code for bank 1 AND bank 2, and is not running right-the car is shaky at idle, and is surging at light throttle-it seems to run better the more i get into the throttle. it also has backfired a few times on start up. it seems to ping a lot more when the motor is lugging. i checked for any visible vacume leaks and cant find anything. i thought it might be the 02 sensors, but it seems weird that they would both go at the same time ( bank 1 and 2). im going to get the car tuned as soon as i can, but can some one give me some ideas as to what might be going on? i dont know if this is something that can be fixed with a tune. thanks!

car is now throwing P1133, P0300 (random/multiple misfire), P0171(lean bank 1) and P0174(lean bank 2). i popped the hood and revved the motor a little and it sounds like there is a ticking in the driver side head.... which can never be good.
