    Check the PCV grommet in the rear (bank 1) cam cover. If it's loose, you have a vacuum leak in bank 1. Check ALL the vacuum lines and connections, not just the manifold mounting.

    AND WE JUST broke down. It seems like the brakes jammed and we can't move.

    I chased a lean bank 1 leak for about a month. I had 6 vacuum leaks. And bad intake gasket.
    Also found out I had a bad icm.
    Hope you find it soon.

    Dads taking it monday morning to his friends shop to get the o2 sensor changed. He didnt have any room to do it himself. So it'll be easier to give it to a mechanic. When I get back to l.a from Arizona ill post my outcome and if it passed smog!
