EGR stall test question

[zukitrek]

I guess the diameter has to be an specific size, i mean I should not widen them? Let me tell you I did inserted a hangers wire tip at a 90 degree angle from each intake opening and then a long wire from the EGR port and lots of crap came out until I could blow air without restrictions(did not use any cleaners or degreasers) , but this was very late at night and car had to be ready next morning. Having tested almost everything this code 51 points to clogged mini ports from HELL!!. I did my best but I know it was not enough. I will do it friday night and let it soak in degreaser or bad idea? One thing there is not much space in those output ports right? How can drilling be possible?

Yes bark test was done, with video and you mentioned that it passed.(exhaust 4 port seems clean) as well as cleaning 3 times EGR main and testing diaphragm (need to do the leak down test though).

You mentioned in a past post in this thread to bypass p-q nipples to test EGR main, using a long hose connected to a TB port? Could you specify which is the one?

Thanks!!
