Thanks. Rookie mistake. It’s a 2003 Boxster S, manual trans.
What’s puzzling me is that it’s just a short burst at tip-in, then goes away. I would think a vacuum leak would be steady. Maybe it’s normal induction noise that I’ve just never heard before with the covers on.
I can do some digging. Maybe a smoke test. I’ve found that usually any problem I’m having has been had before, so thought I’d start here and see if this is one of those obvious things based on collective experience.

Seriously. We need to know what you're driving because these 986s have technical/parts specifications that are all over the map. Maybe include that information in your signature.
A hissing shuld be easy to diagnose, and absent all that ancllary information you provided. Get one of the stethaascopes devices and start poking around with it. In the alternative... remove easy to access hoses one at a time and listen for the hissing to stop. You might find the problem. Good luck. |
