Check engine light shows code 13......
Hey guys My check engine light came on the other day, twice now.. I flashed the codes and came up with code 13 just that single code too.
It something like O2 sensor reads lean engine at cruise when warmed up.
My car has ALL of the AIR components and the cateletic converter thats stock But my car has nothing after the cateletic converter (no cat back...) Car sounds really cool with out it but is this code going to make my car run funny/get bad gas mileage??
