Hey, I got to talk to Joe when I was having emissions problems - great guy, very knowledgeable. He checked some things on my truck, then popped one of the air injection hoses loose and stuck a compressed air hose into it, then ran the test to demonstrate that my air pump was weak and that the cat was also weak. Finding a strong air pump is no easy task. The remanufactured pumps don't get new vanes from what I've gathered. New pump are sick expensive. I got a reman pump but overhauled it prior to installation. The quality of remans ranges from ho-hum to crappy. I've dissassembled pumps straight from the parts store find 2 of the three vanes installed. I also installed a new cat. Unfortuneately the combo of the cat, air pump and other misc smog parts fixes still didn't pass the test. It was the Jim C rebuilt carb that finally brought the CO way down. HTHs,

Bruce
