I tested the EGR Valve and it appears to be okay. The diaphragm looks solid. I pushed it up and put my finger on the port. It held it in the up position until I released my finger ten to fifteen seconds later. Is it worth replacing while I have it off? I have heard they last quite a while. I have to replace the EGR Valve gasket as it broke during removal.
While at the parts store looking at a replacement EGR Valve, I noticed that the range of motion on my old valve in the passageway was not as much as the new one. The diaphragm appeared to have full range of motion.
I decided to replace the EGR Valve. Upon startup, the check engine light did not come on. I will drive around the car for two hundred miles and bring it to be smog tested. I will update when that happens.
Do you have any other suggestions? I think I am approaching the limit of what I can do in my driveway. Thanks!
