Running Snail, thanks for the link and the advice. Sounds like my vcv is bleeding off vacuum too quickly, like I said I think like 1 or 2 seconds with the engine stopped and no throttle. I will check again tomorrow and report. If Diesel Dan was correct when he stated the vcv should bleed off 1 inHg per second, I think mine is going much faster. One thing, though: my car is an '87 and my vcv looks quite different than what Diesel Dan pictured. My car was worked on by someone who had no clue about diesels and they replaced the injection pump. When they did so they did some stupid things like not replacing the injector line retaining clips, and smashing the alda against the intake and cracking it. Sooo I wouldn't be surprised if they messed up the adjustment of my vcv before putting it on the new IP or if the thing was bad and they put it back on because they had no clue or didn't care. I will report back and thanks for the help.
Sean, stay tuned maybe we can help each other.
