Hello, Sixspeeders
911 is always my dream car and I just finally got an 07' C2 after years of hard work. It's been a wonderful week but after a couple of rainy days she starts making ringing noise. I suspect one of the pulleys might causing it. Do you know if I can run the engine with the air filter box remove ie. MAF sensor disconnected to gain better access to the pulleys?

 

You can and I even did so today. I find that when I do it, I have to give the car a little bit of gas for the first few seconds of starting it but just a little bit so it won't stall then the ECU will adapt to a baseline and idle just fine.

 

Congratulations on your new addition. Good luck.

 

never tried but the rain does make the car squeal temporarily if enough gets on it. don't think that is abnormal.

enjoy!
