a non-functioning egr system won't hurt the car/engine at all... it is just an emissions thing (egr = exhaust gas recirculation - the system takes some of the exhaust gasses and recycles them through the intake so some of the unburned contaminants get burned up the second time through, making the exhaust cleaner from an environmental standpoint). the egr system is *required* to be functioning properly and not clogged in california - your car has to pass a smog test every year in order for you to renew your registration in california...that is why it is a big deal over here. if yours isn't working and you don't need to pass some sort of emissions test in your state, then i *definitely* wouldn't worry about fixing it. when i had bot of my legends tested with the blocked egr system, the exhaust itself couldn't have been cleaner - it was like 0% carbon monoxide. they were both failed by the mechanic because when he physically tested the egr system to make sure it was working, it was not (basically, using a vacuum pressure reader, they apply a vacuum force to an inlet in the engine bay. if the engine dies, then the egr system is functioning. if nothing happens, then the system is clogged.). let me know if you have any more questions...
