Rough idle

[atruj213]

I have a 2000 Explorer V6 4.0 L OHV. I am having a rough Idle wheh the engine warms up. I have cleaned the MAF, IAC, Throttle body, and replaced the air filter and PCV valve. I pulled off rhe throttle body and took a look inside the intake manifold. I noticed that there was a little sensor sticking out that was corroted. I don't know the name of this sensor or know how to replace it. IT IS NOT THE IAC.

Here is a picture from the outside. The metal tube coming off the sensor is gold and looks like it conects to the EGR valve. If anyone could tell me what this is and how to remove it.

sound like a evr or a electronic vacuum regulator best thing to do is check it before you pull it the test on it is extensive but you can get the procedure at any autopart store in a haynes or chilton book
