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 simple cure: disconnect the vacuum line. Pressure. If the charcoal bed is clogged with dirt (there's no filter on the air intake of the canister), you tend to get vacuum in the tank while the engine runs. Pressure in the tanks leads me to suspect that there's a blockage in the pipes leading to the canister. - - Jan. ** Never let a machine know you're in a hurry ** Tom Russ Adds for the Series III. The pressure in the fuel tanks is actually a normal condition. The fuel tanks are vented to the engine's purge system via the charcoal cannister in front of the RF wheel arch. But, installed inline just before the cannister is what is called a two pound check valve.
