Has anyone taken off all of the smog stuff, and anything not really necessary for the engine to run? I have the smog pump off and all of the tubes running from it. There is also a tube that connects the rear of the heads together. That is now gone. My question really has to do with the EGR valve and what looks like a solenoid and bracket with two relays on the rear of the throttle body. The solenoid and relays have a few vacuum lines going to them. I'd really like to get rid of them if they aren't needed. Also, is the EGR valve really necessary? If so, what exactly does it do. I have the factory shop manuals and they don't say anything about it, so I assume it may be in the Smog/Emissions shop manual which I don't have. Any help is appreciated. I have a 93 if that makes a difference.
Thanks,
Doug
