slew of codes, help! alright, car is throwing p1133 (a/f) p0300 (random/multiple misfire) p0171/p0174 (lean bank 1 and 2). is it possible that the 02 sensors are both bad and they could be causing this? there is also a sound coming from the drivers side when i rev the motor, i cant tell if its in the head itself or by the 02 sensor. i hope its not a bad valve 
i still have 2 02 sensors left from when i put the headers on, so maybe i can switch them in and give it a try? or should i just bite the bullet and get vette 02's? there is also a small leak at the driver side collector, i read that could cause a problem if the leak is 6-12 in. from the 02. thanks guys!

you are having misfires, is everything ok cylinder wise and such? pull some spark plugs or something.
the vette 02's won't help
what kind of sound? how bad of a leak is it

the leak isnt terrible, i've had worse. im goign to get a new clamp and start from there. the noise is a rattle...and it sounds like its coming from the head/header area. you can hear it almost as well under the car as under the hood. is it possible that having the air system hooked up is causing the lean code being that i dont have cats?
i'll pull some plugs tomorrow, it just seems weird that the code is for both sides but the noise is on one.
