P 0171

Got two codes showing.

P0171 "Bank One system too lean. Parameter at Maximum"

C1109 "Battery voltage abnormal"

I will go use the search function now but wanted to know what you guys had to say.

'08 G37S

Stock

Thanks
David

the p0171 might be a bad O2 sensor. or maybe a leak some where in the intake

the c1109 might be a bad battery. get it checked. if normal maybe a bad alternator.
