is your EGR operational ?

On my EA82T I simply used a T piece to T in a 2m length of 4mm vacuum washer hose at the EGR vacuum inlet, fed through a firewall plug hole to a spare EGR valve. I guess I could do it without, just testing whether I have vacuum or not during EGR supposed operation. I just stuck my finger in EGR valve in cabin to feel when it works. It does not work as described in factory manuals on my 87 EA82T. It is supposed to be inactive until operating temp and also above 45 kph. It is active whenever the vacuum is about 1 to 10 in Hg - maintaining light cruise throttle. It was easy for me to keep my finger on it driving an auto.

It should be safer to test with an observer / driver combo
