EGR stall test question

[zukitrek]

Ok. More results. ECU did energized and closed vSV when car started.. I did it in reverse order but it porved ECU energized it and close it. Then took connector oof and I could blow air thru VSV nipples. I then used TB vacuum port and ran a hose to P nipple and car rpm went down and shook a little like when doing EGR main test with hand (4 ports from hell in action!!). I then energized the VSV again with the connector and it closed it again, and then I blew air and it went out C port (filter).

So we deduct:
A-ECU is closing VSV when engine on
B-Passages are not blocked at VSV
C-Mod valve is also working as rpms went down when using TB vacuum port to P nipple thru the disconnected VSV passages

One doubt only. I measured the volts at the white/light green connector but never got the 12volts, but connected it did close the VSV. To make sure, red probe at connector black probe at engine and what range setting at DMM?

So all it needs is cleaning those damn 4 tiny holes at the Mani!!

Will let you know results. Good night!!
