EGR issues

[Dagostino480]

Hey guys, I bought another s14 and it has a p0440, p0135, and a p0325

Don't hold me to those numbers haha cause i looked it up about a week ago. I know its an egr code, o2 sensor code, and a knock sensor code.

Knock sensor code is due to my bad knock sensor which is coming in the mail.

O2 I haven't gotten to yet

Egr code is being diagnosed as we speak but i cant find the issue. The egr functions as should because when i compress the bottom plate the engine bogs down. And i ran a cleaner through it. So i followed the vacuum line to the other valve next to it. The egr is getting zero vacuum as well as the other valve. I know the other valve has and exhaust tube underneath it and that is kinked but it should have anything to due with zero vacuum.

I did vacuum tests on both valve with the car stationary and accelerating as well as the car in motion with the result of zero vacuum...didn't even budge.

Can someone shed some insight please?

And I'm in California and I'm wanting to keep the egr system so a delete is out of the picture

Im in the same boat you are in,but I figured out that kinked hose on the 2nd valve is common,so when I had the intake off I replaced every vacuum line and my knock sensor plus my egr gasket even though its a metal one,but now my car idles below 1000rpm like it should,but I got a fuel issue now,so I'll give you an update after thats fixed
