Concure with Schrade.Also the 4 ports located inside the intake manifold are prone to clogging.The result will be hi exhaust gas temp(can be seen using a Consult 2).If you do remove the ERG valve make sure you have a new gasket to replace the old one.To get to the exhaust ports look at the manifold and you will see 4 counter sunk hex plugs. Under each one there will be a port.I've seen this many times and sometimes the ports will become so clogged that it's difficule to see the ports but they are there.
