At idle I noticed that one of my injectors makes an intermittent hissing noise. I can't remember if that was normal. I am just trying to start to drive this thing again. ![[burnout]](graemlins/burnout.gif)

That doesn't sound normal...Is your car idling ok, is there any other drivability problems?....
Do a search on the web for "injector balance test" and that should help you....And obviously make sure it's not leaking....
Good luck!...

mine did the same noise, my problem was that it was leaking. id smell a little bit of gas too. check around your lower manifold for any leaks or gas smell ![[patriot]](graemlins/patriot.gif)

sounds like a bad O-ring on the injector.

That's what I would do. Also, coat the o-rings with a light coat of oil to help them seat. You can get the o-ring kits @ Pep boys. They come with the upper and lower o-ring as well as a new cap.

Well, it is not leaking yet. It idles fine and passed smog this morning. I am just gonna run it til' it gives me another sign. Fortunately, they are just the stock 19lb'ers and it is the #1 cyl. injector in plain view.
