OK, I will get the read from the correct line as soon as I get back to the car. What is the expected read ?

It should start out fairly high...........15" or so...........and get proportionally less as the pedal is pressed further down. The gauge must be observed while driving the vehicle and the various vacuum levels noted during various operating modes of the vehicle.

That's the line.........put a gauge into that line with a T.........and watch the gauge while you drive it.

OK- 23 in/Hg coming into VCV, 3 in/Hg going out. Pulled the vacuum on the VCV and it is not holding. Please advise. Thank you. |

Connect the vacuum gauge directly to the output of the VCV, instead of using the T...........see what you get when you drive it. |

I will do that test tomorrow (getting dark already). Is there anything that can be fixed on that valve? Are they pretty expensive?

Don't know if anyone has successfully fixed one of them............and, yep, they're pricey.

I thought VCV's weren't even available anymore? Or is that only on 123's?

Apparently you can still get them ifor w124 f you have about $160 to blow... I need to take the bad one off the IP and take a good look. I'm hoping that maybe there is some kind of "stuck" part that makes it think the pedal is to the metal and the "controlled" leak is to the max. Lets hope it is not a PITA to dismantle....

OK, I have done it: VCV valve taken apart as per very helpful DIY aricle by sixto. The tiny rubber pad that comes up against the metal orifice providing vacuum source developed a hole in the center. Unlike sixto, I was not observant enough and lost one of the springs from the valve assembly (the bigger one). Unless I find it, my success wil be partial: I will know why the valve was bad, what I might have done it to fix it, and than get a new one since I lost one of the parts. So, anyone afflicted with the bad VCV valve follow sixto's DIY "how to" write up and you can save some serious money if you are more careful than than I was.

Last night I got a used VCV valve for $60 and it seems to work great:14 in. output. Over the weekend I'll try to get the read under the load for my own curiosity but the hard shift is the thing of the past! Thanks again for your guidance.
