Typically those smog pumps seize up and people remove them or the belts. Or they just remove them because they are a drag on the system and not needed in certain areas.
My 420SEL is like this, I removed the belt as Ohio doesnt test emissions and it doesn't really do anything other than introduce air into the exhaust.
As to your stumble, look around for vacuum leaks. Some of those plastic hoses tend to get brittle and develop cracks. Check at the EZL ignition module on the driver side fender, that will cause some good stumbles.
