Environmental psychology addresses environmental problems such as density and crowding, noise pollution, sub-standard living, and urban decay. 1  Noise increases environmental stress.
Hayapower is correct. The tube from the converter is for the smog pump (air injection) for the catalytic converter. The EGR tube comes off the passenger side exhaust manifold. Disconnecting the tube from the converter will not hurt if you remove the conveter and close off the tube end or leave it open.If you leave it open then at times you will hear a pumping sound from the tube caused by the smog pump when it reaches proper temperature.t's thermactor/secondary fresh air injected from the smog air pump for converter/catalyst secondary burn/conversion.. Disabling/restricting an EGR flow (drastically), can/will result in a DTC.. The tube is needed for a fresh air suppy to the converter..
The air pump is only used for smog purposes, and will not hurt your car if it is disabled or removed. Some claim a lumpy or hunting idle when it's disconnected, but may others have no problem. I have been told that removal of the air pump will result in the early demise of your catalytic converter.ou must remove the sensor on top of the valve and tuck it under the plenum so you do not get an error code. D) Get the Greddy pulley kit so you can drive the car w/o the air pump in place. This really cleans the under the hood up.
