Sam,
Chances are that your catalytic converter is shot. That's an expensive
repair. :(
I have left the air pump disconnected on mine because of that. Plus, my
air pump is a bit noisy also. (Another expensive repair) It passed the NJ
idle emissions test that way... :)
Also, there is an off chance that your bypass/deceleration valve (front
side of carb) has been blanked off.
