dux, what exactly do you mean by look at the valve and map sensor on the fender? I am fairly new to maintaining the car, so I do not know what you mean.

Also just to clarify, my current issue appears to be the SOV is not working even though it is brand new... I am getting vacuum to the SOV but not past it, so the EGR isn't opening up. It worked briefly but seems to have stopped working, so I am going to speak to the vendor and see if they can replace it or give me a way to test for proper function. Outside of that I am stuck.

I hope it helps with the idle because I am running out of things to replace/fix to smooth it out hah.
