Answer 1

Hi there,

Based on your readings i would check for an intake manifold gasket leak around cylinder #2. You do show a problem on bank 2. With the engine idling, spray some carb cleaner along the intake to see if there is any change in the way it idles. If there is, then you know you have a leak
