long story short, i threw a few codes. Got one fixed so far P0401, by changing the vaccum solenoid. now im throwing codes P1131 (lack of bank 1 02 transitions- lean limit) and P1151 (lack of 02 switches-bank 2 sensor 1). any idea what would cause me to throw these codes and the fix for it? thanks in advance.

 

Im not sure but I think those are the same codes i threw not too long ago it had to do with my maf sensor being dirty cleaned it and reset the computer and hasnt come back since if both banks throw a code it usually points to a bad or dirty maf sensor

 

cool. ill give it a shot. what did you use to clean it?

 

just get some electrical parts cleaner and spray it down real good, it comes in an aerosol can
