Vaccum question
My car at idle is running 17 in HG but the needle is very shaky. does this mean that I have a vac leak or that something else is wrong with the car. I am contemplating replacing the engine but i would like some outside input from somebody with a little more knowledge.
thanks
Adam

Where are you measuring the vacuum? Off the empty nipple on the right side of the UIM?
If so you may just need a restriction in the gauge tubing to damp out the pulsations.
What is your idle speed? Do you have any other symptoms of engine problems?
If not, it's probably just the gauge responding to normal intake pressure pulses.

yes off of the extra vac nipple on the uim.
the car does have a sticking idle which is related to the brakes most likely the check valve. and a little studder of the engine that i have not been able to figure out yet
the car is stock with 65k on the odo and new silicone lines and check valves for the rats nets.

This, however, is probably unrelated to the gauge flutter.
