the "slight hiss" may be a vaccum leakPockets wrote:So I've been noticing a vibration when my Pathy is idleing and I'm not sure whats cauding it. I put a bottle of techron in the last time I filled up and I'm 1/2 way through. feels a little better but still not good. There is a slight hiss near the intake as well. I'm about to add volant CAI and new mass air sensor with new plugs and wires but I want to make sure I'm ot missing anything. Advice?
