This is something quite peculiar and I've noticed it going on for only the last two weeks. From a standing start I hear a weird sound similar to a police siren when someone is being pulled over. Not a non stop sound but rather 2 quick " whoop! " 's. I have no idea what this noise couldbe as it only happens every once in a while. ( three times in the last two weeks )



Everyones input is greatly appreciated.

 

come to our weekly meet and someone should know what the noise is...

 

I would like to, but it's a problem that randomly appears... Otherwise my mechanic would be all over that right now.

 

its not when you first start the car is it??? thats the air pump, or just go to the meets

 

No, its not when i first start the car. If anything I think it happens shortly after Ive started , and say I'm exiting a parking lot and turning out onto the main streets. But I think one of the instances happened at a red light turned green at which time I had already been driving for a while. Its quite baffling

 

Maybe sticky brake pad? Just throwing ideas out. I say go to the Wed meets and maybe you can at least explain the noise better to one of the guys there.

 

With A/C on ? if so i think the noise is from the a/c expension valve.
