Hey I’m new to the forum but also new to the car scene as well. I recently purchased a 93 Toyota pick up. I need help finding this part but I can’t find much information on it. I think it’s some sort of egr vacuum selonoid . If anyone has any info on it it would be greatly appreciated

That's called a Vacuum Switching Valve. Was it mounted to the valve cover, say maybe in the front of it? Like towards the radiator? Had a vacuum line and electrical plug on it?

You should have a vacuum diagram on the upper, left corner of the hood. Follow it's vacuum line to wherever it goes, and then look on the diagram to match the VSV to what you see. It might go to the EGR, but it might be for the fuel pressure regulator at the real of the fuel rail, or whatever.

Two things that would help us a lot to help you. First and foremost, what is your truck's year, engine type like 22RE, 22R, or 3VZE, etc, SR5 or DLX, mileage, and so forth. Put it in your signature, like you'll generally see most people do. Like my signature, for example. Mine isn't perfect, but it's not that bad.
Second, a picture of that part in place on the engine. A wide enough shot, we can see where it is relative the other various engine parts. Perhaps with the part you mean circled or otherwise indicated on the picture. An arrow, a circle, something. It's worth a few thousand words to us. Maybe a picture of your truck's vacuum diagram, too.
The more information you give us, the more, and more accurate, help we can give YOU.

Foes this help a little?
