New (to me) GT running lean

Hey guys, I've been in the V6 forum for a while and my old man just bought a GT. Right away its throwing a code for running leaan, i pulled the MAF and cleaned it and then cleared the code but it came back. The car has a CAI and axle backs, but theres i dont think that would be enough added air flow to make the engine run lean. Whats my next step in fixing it? Thanks

on an s197 a CAI can cause it to run lean unless it's tuned for it

someone may have put a stock intake on it with a non stock intake tune or something like that etc

I dont believe its tuned, so . But just having a CAI could make it run lean, thats sweet/blows
