stalling and code 76

[VSIIBerlinaL67]

since i have put a larger throttle body and a performance chip on my car, it stalls when i press the throttle very lightly and when im slowing down to go around a corner, the engine, battery and oil light comes on when it stalls,
and also it takes a few more cranks to start it

its a V6 VS auto, i checked the codes and it came up with this..
Code 76 - Air/Fuel ratio variation between left and right banks

what can i do to fix these problems

thanks

leaking exhaust or inlet manifolds
