classic brake booster problem the seal on the brake booster is leaking it will get a lot worse eventually you will loose enough vacuum that the engine will die when idling and you push the pedal down a bit I would go ahead and change it out before it gets that bad.These are a challenge to change out I have put two on my 97 chevy truck 276k the last one just a few months ago. A good knuckle joint for your long extension is a must along with a air ratchet of course. Oh and be sure to use some duct tape to seal the top edge of the carpet cause the stupid nuts will fall behind the carpet edge into never to be found again land LOL
