I have a 2005 Dodge Caravan SE with a 3.3L V6. My engine light came on about a week ago, and upon pulling the code, I came up with a P0404 or EGR Valve. I work for Pep Boys as an installer, and one of the mechs at work told me to try cleaning out the EGR valve with throttle body cleaner. I sprayed the ports of the EGR valve with throttle body cleaner and then disconnected the positive battery terminal to reset the computer. The check engine light came back on with the same code and the car is still sputters every now and then. The sputtering seems to happen when it's hot outside and the vehicle has been running for a while. I've unfortunately already discovered that the EGR valve is not covered on my warranty. Are there any additional steps I can try, or should I just chalk it up to a bad EGR?

My vans fuel gauge doesn't read. It has double tanks w/2 sending units & fuel pumps. I thought that even if one sending unit was defective the other should work so I replaced the fuel gauge but that wasn't the problem. There is power going to the gauge. What should I do next? Help please!
