That port on ZRVette's pic has to be connected to underside of your MAP sensor. Your MAP sensor is under aluminum trim behind the plenum held on with 2 black torx head bolts.

Make sure that vacuum line is hard plastic (non-collapsible) with rubber fitting on ends only to slip over plenum fitting and over MAP sensor nipple.

So... from all acounts thus far l could have popped the MAP sensor hose....or at least l hope l have as it seems l can get to that one easily ans lve checked all other more visible conns

does the MAP connection failure explain the grumbly start up until l blip it and the SES comes on

if its the case and l fix it (or other hose leak).....then l think l also recall that l cant clear the code by just a battery disconnect......?

will it need a scanner tool to clear it?

Disconnected MAP vacuum hose will make the car run like hell, including grumbly start, and trip SES light.
SES code can be cleared by disconnecting the battery for about 30 seconds plus, if I remember correct.
I am sure someone will chime in and correct me if wrong.
Also, make sure you use factory MAP vacuum hose or fabricate out of hard plastic except for both ends. Soft hose will work for a while until heat and oil soften it at which point motor will stumble at high vacuum condition (low rpm). I found this out the hard way.
