    The saga continues... Looks like I see soon soot under the bolt for the support bracket that he used his handy dandy acetylene torch to burn the bolts off rather than remove the bracket from the transmission housing. Time to call around to see if I can find a gasket.

    O2 sensor readings are supposed to swing high/low.

    Damn that is a lot of rust! The heavy duty gaskets from URD are really good!

    Shhhhhh. I'm going through the easy/cheap fixes first. This code appeared after a motor swap. And I'm kicking myself in the ass for not doing this myself with what I'm finding as I'm working on this... Missing, loose hardware... Why break out the torch when removing 2 other bolts accomplishes the same thing?

    Now that I see this soot, I'm hoping this is the fix.

    Now the question: do I have to break the other side to replace this gasket between the cat and the resonator?

    New gasket and nuts for one side, $28. Ouch

    Edit, I must be going deef, 14 and change...

    Yes. Both will need to be un-bolted.

    Quick easy and for the most part, painless. It looks like someone couldn't be bothered resetting the gaskets properlyIMG_20161016_120509.jpg

    I'm am indeed a happy camper. I reset the light and put about 10 miles on it. Id think the ecu would do is efficiency(lean,rich) test in that time. Letting it sit now for 10 minutes or so and then gonna do another drive cycle.

    I Have the P0420 and P0430 codes and I've lost coolant. Is there a correlation and/or do you have some insight?
