Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
New plugs (they were due) torqued to spec, and new coil packs (frosting on the cake)...problem solved.
I took my Boxster into the shop today to diagnose a "chirping". It really sounds like a belt noise but I took the belt off and the noise remained so off to the shop it went. They spend hours with a scope and found the noise to be coming out of the front center of the engine. I'm not sure if I want to invest a ton in tearing the motor apart but might try a shot in the dark with timing chain tensioners. Do you think that could be it? Any other ideas?
More "chirping" info
The chirp is the loudest at idle and then goes away as the revs climb (as oil pressure increases?). The chirp is sometimes just a single chirp and other times its continuous.
Thanks guys

Hope this is a fix for you....cheap!
When was your water pump last replaced? When the bearing in the pump in my car started to fail, it exhibited the exact sound and symptoms you describe. It may also be starting to weep a little coolant.

Read post #12 in the thread I have attached. Mr. Raby describes a squeak from excessive vacuum through the main seal from a failed AOS. I would think this could be verified by attempting to pull your oil cap with engine running. Since vacuum is greatest at idle and drops with RPM could be the cause. Location is also appropriate. Good Luck.

This is another good one. I'm feeling pretty good about the loose plug, the car also has a new exhaust leak from one cylinder (I thought it was from the headers( but I bet it's the plug). Crazy....
Hi guys, I started hearing a chirping noise when car isn’t driven for a couple of days. Noise disappears after 10 to 15 seconds. Noise still present with belt removed. Anyone resolved this problem? Thanks ��
Very common cause for that in these cars is a slightly loose spark plug. It starts chirping (kind of like a littel bird) usually when the engine heats up a bit.
Verified the spark plugs today and found a loose one let’s hope that was the cause of the noise. Thanks for your help very appreciated, all the best to you from Canada
I'll bet addressing the plugs will fix it (probably in both cases). I had the same thing a couple years ago. "Chirp" is the word that perfectly describes the sound the car was making.
