I have a 1996 Firebird 3.8L that has had several instances where the service code indicates a bad EGR valve or EGR sensor (forgive terminology mistakes, please). I've replaced the EGR valve once and the problem has returned. Checking the spring and obvious visuals, I see nothing wrong with the new one (2-3 months). Is there another module or another problem that could be causing this? I also have a coolant smell as though the overflow is just venting but no real loss of fluid nor over heating. I was thinking maybe the catalytic converter was getting plugged and causing some sort of back-pressure but that's just a wild guess. Any suggestions or experiences?
