    i know the feeling, if it is something simple i will do it myself, but when it comes to a difficult issue i rely on an experienced tech.

    from what you describe i would have pulled the heater core and see what it looked like and if fluid was flowing through it.

    Wouldn't be the first time there was an air bubble caught in the system after the last refill of coolant.

    The coolant issue seems to have bled itself out, and I'm not hearing the bubbling anymore.

    The shop diagnosed my two codes as both being caused by a bad catalytic converter. I am looking at magnaflow 23457. Are there any other high flow, or high performance options for cats? In the next few weeks/months I'd like to go ahead and do a cat-back exhaust.
