But when you pinch the ends so only a little air gets out at a time so it goes EEEEEeeeeeeEeEeEeeeeEEEEeeee
That's what my car is doing! It started the day before yesterday but it didn't do it yesterday and it started again today. The pitch changes when I hit the gas.
What could that be? It's driving me nuts. I even hear it when I'm not driving, now.
