Possible Vacuum Leak?
I have a 1995 that runs strong. I noticed the other day when the hood was open that after I turn the car off I heard a hissing sound for a few seconds coming from under the intake (of course....). I don’t recall ever hearing that before. The car doesn’t seem to do it if I start it only for a minute then turn it off. Running the ignition on with engine off vacuum pump test indicates no issues with at least that part of the vacuum system.
