Vacumn line for front engine mount

How important is it? Cause the shop that put my front mount back on didn't install the vacuum line. After I handed the hard line & rubber hoses to them with the new mount. Yet I don't see those parts in my car or hooked up to the vacuum sensor so they must have kept them.

It is very important. The vacuum line is there to control engine NVH at idle and over the RPM range. Without it connected, your engine mount performance is compromised.

Get it hooked back up.

Fuzzy, same thing happened to me when I had mine done, I let it ride for a few days and on a long drive to houston (3-4 hours), at an idle the rpms would jump from 900 to about 3100, back and forth... everyone at redlights thought I was trying to race them....
hook em up

Its important. It needs to be installed. It helps with vibrations, and without it it may tear it up faster

The vacuum sensor is plugged, so no leak.

IDK, the car seems to be fine. Getting no more vibrations then I did before with stock mounts.
It's going to be a royal PITA to get the shop to put it on. I'll have to take off work drive there & then hope they still have the line in the shop.
Will they have to remove the front mount to plug the line in? The parts new are $10, If the mount doesn't have to come out again to plug the line back I may just buy the parts & do it myself.

That's the idle air control valve not the engine mounts.

just leave the line plugged. if you did what i think you did w/ the poly, then don't worry about it. otherwise the connection is on the underside of the mount as i recall.

PITA!
My fat fingers had problems getting the vacuum hose onto the nipple that was buried under the front mount. There was this little gap under the mount. Took me a day to get it. I got it on in 5 minutes, then pulled the line out as I routed the hard line
Then couldn't get it on again till today.
