Quick question for the brilliant automotive engineers and experienced shade tree mechanics on the forum. I have a '94 with a check engine light on. The code directly relates to the EGR valve. I have replaced the sensor but no joy. Today I pulled out the EGR valve and stem that connects to the exhaust manifold. There is a 2 inch crack on the bottom of the stem. My question is this - would the crack cause an issue that would make the DPFE code pop? The two stem pipes go in and out of the DPFE. Is/would the crack cause a pressure related problem here?
FWIW the stem is over at dad's getting welded this week and will go back in the car with a brand new EGR and new DPFE (since Autozone warrantied it back).
If this doesn't work I'm going to look at EGR deletion - perhaps that will get me closer and closer to buying a quarterhorse.
