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 symptoms you describe point to a restricted exhaust system, and 90% of the time that means your catalytic converter has failed, and will need to be replaced. Yes, you will need a muffler shop, and if I'm right, it's going to be expensive, sorry.oklatom Â· 8 years ago.Thumbs up.hey also told me that there was an exhaust leak after the headers but before the cat. converter and that the same O2 sensor that was right there was bad to but they could not fix and I would have to take it to a muffler shop.
