Removed Smog Pump, Failed Emissions?

i passed emissions without the smog equipment on my car. Just make sure your timing is at 10* and that the car is at operating temp when they test it.
It is very dependant on the individual car and the state or local requirements. Some states or areas may have stricter regulations on the amount of pollutants the car can emit.
Running cats with no smog pump will eventually cause the cats to clog up & fail. High mileage engines burn oil that ends up coating the inside of the cats and clogs them. You may not see any evidence of oil burning, but it is still happening if you have a lot of miles on an engine.
The smog pump provides extra air to react with the exhaust and the catalyst and break down the pollutants into CO2 & water vapor. It shuts off at Wide Open Throttle so it doesn’t use any real power when you want all the power you can get. It just doesn’t make sense to disconnect it on a street driven car.

Yes it does. I got sick of them seizing up and leaving me stranded. Happened to me three times with recondishioned pumps and then one more time with a brand new OEM ($325!) Ford one. It's one less pulley in the loop that may give me problems. The power steering is next...jrichker said:

If you have cats, you might as well hook it back up. I took my smog pump off because I got tired of a "brrrr" sound coming from under my car from where the pipe wasn't connected to the exhaust.

What the hell are cats and a smog pump 
On the eastern shore of maryland, we don't have emissions. Godbless rednecks and their farm truck ways.
