Weird 'chirping' sound, 2001 Boxster S

[FoFoJoe]

Interesting, I never would've guessed spark plugs. Wouldn't hurt to inspect or replace your spark plugs, spark plug tubes (or just the o-rings), and coil packs depending on mileage and service history. I'd be worried that taking a coil pack out could kill it if it's already about to die. Could crack the plastic or something like that.

ECS sells ignition kits.

Granted I would only worry about that if the car is 120k miles or more without any ignition servicing. And if you take the spark plugs out, replace those at minimum. No point in installing old plugs given how inexpensive but important they are.

Chirp is gone.

My kid, having read this tread, said we ought to diagnose the problem, at least to the point of checking the loose-plug theory. That's what started us down this pathway that tied up the car for like a couple weeks.

First it was the plugs. Decided to do the coils as well. None of the plugs seemed "loose" but some did come out without hard cranking on the wrench...so they probably were.

Then it's like, "Well, she's on the lift, the water pump is like 11 years old...do we do a WP/thermostat before taking her home?" He's totally game. So then I say, "Well, if we're emptying the cooling system, maybe we should do the coolant expansion tank before it develops the inevitable crack and starts wetting my trunk carpet." The kid's like, "Sure, let's do it."

It's absolutely terrific having a son that likes to wrench! :dance:

Frodo, it's actually a blessing as I have to beg my kids to help me with the heavy wrenching (suspension repairs, etc.,) and now that both live out of the house is harder, aging sucks.. :ah:
