It is a safe bet to say you are running too lean. Now if this is what caused the code, I cannot guarantee that. If one of the O2 sensors was damaged you would probably throw a different code, so we can rule that one out. I would say it is time to get your car on a dyno and find out what that A/F is doing. If it is lean, you will need a tune. If you cannot afford a tune then put the stock intakes back on the car for the time being and I bet ten to one your A/F will go back to where it needs to be...
