Hey, just wanted to say thanks guys. I looked up the schematic for the secondary air flow pump like you said, studied all the parts, inspected my engine bay, and I think I see the problem; The vacuum tubing just after the metal housing pump is very nearly crumbly. Very old looking. The intake side 1" rubber tubing into the plastic pump was loose as well. I think I just need to get some of these tubing parts replaced. 96k... they're probly fried, or soon will be.

So thank you so much. The knowledge level on this forum is so high. Awesome group!
