I have a 2010 rs/ss with cold air intake / long headers / magnaflow exhaust / Diablo sport tune . I had put on about 2000 miles and have 8500 miles on car today ... I get engine codes come up three times which read P1133 Bank 1 fuel control and P1153 bank 2 fuel control come up.... Has anyone had this come up and if so what do the codes mean running lean? Thanks

 

this is the reason i had my car taken in and professionally tuned. you may want to concider the same thing. they can always get more power out of the car too.
