It sounds like I have a header leak but I'm trying to figure out which side before taking it apart. The long term fuel trim on bank 1(driver's side?) is running about 7-10 lower than bank 2 during cruise conditions. I'm interpreting this to mean that bank 2 is reading lean and adding more fuel. At cruise and idle the header leak would be sucking in air through the leak thus causing the lean reading. So this makes me think my header leak is on the passenger side(that figures). Anyone have any thoughts before I waste my time on that side first. You just can't quite hear where it's coming from when you rev the engine while in park.
