Hi there. If you are getting the EGR valve to operate in the opposite times, then check the harness for power and see if the power is on with the engine at idle. Check the voltage and there should be a 5 volt reference going in and 0 reference going out. If the valve has a 5 volt reference going in and a 5 volt reference going out while the engine is at idle, then the valve needs replaced. If the valve has a 5 volt reference going in and a 0 volt reference going out while the engine is at idle, then the computer needs flashed (reprogrammed) or replaced. If you need further assistance with your vehicle, then seek out a professional, such as one from Your Mechanic, to help you with the EGR functioning incorrectly.
