ProtegeSpeed303

Ok, I was at the dealership the other day test driving a MazdaSpeed Protege and i loved it. It had the HKS BOV on it which sounds amazing and it seems to run really good besides the bushings which i heard go out on these alot. Bu the one thing i was concerned about is that the air/fuel ratio gauge was jumping back and forth from lean to rich when i was sitting at idle. Is this a normal issue with these? or can any aftermarket parts cause that? Thanks!!!!
