    I wouldn't recommend it. The EGR system provides for faster warm up and actually can help to balalnce engine vacumm. When left in a non-working state, it can increase fuel trim.... it can cause a rich condition .... and lead to premature oxygen sensor failure and poor convertor performance. In other words .... it can cause more harm that good.

    An in-operative EGR valve will simply set a fault code and cause a higher than normal reading of NOX at the tailpipe. So, it will affect your ability to get a state inspection sticker and cause you to pollute a little. Other than that there is no ill after effect that I can think of. What was the code? And what year and engine in the Chrysler 300?
