Default 2000 bravada oldsmobile 4.3
Oh my Jesus please help me. So I have a rough idle and have replaced some parts including a catalytic converter. This hose coming from the secondary air pump is broken and I've been to three shops no one knows where it goes. My NOx is very low. Rough idle and dead spots. No lights though.

If it's "off" the end, look to see where it might have been. Air pump, dunno. I sent you a link that could have the emissions schematic you need.
