I was able to get the loud idle to quiet down after accelerating very quickly on an empty country road yesterday - just took it up to 65 very quickly and it went back to it’s nice almost silent idle. But I know it will come back after the next day of steady rain. If this was a crack in the exhaust manifold, wouldn’t the noise come back after everything cooled off again? It is still running quietly today. ---

You should have gone back to your original post and entered this there: [http://community.cartalk.com/posts/list/2155029.page](http://community.cartalk.com/posts/list/2155029.page) Yes, if the manifold had a small crack that gets quiet when hot it should go back to being loud once it is cool. You need to get the car in front of a mechanic when it is idling loudly. Someone has to figure out exactly what is making the noise. You still haven’t described what the sound is like. “Loud” doesn’t say much. ---

Sorry - I don’t know how to use the forum yet. It sounds like a truck is sitting next to my car - that’s what I thought when I first heard it, but then I drove away and parked at the store and found it was my car. I can hear all four cylinders - sort of sounds like when your heart is pounding when you are scared! It usually is almost silent. Now that the sound is gone, it is idling at a lower rpm - more like 500 instead of just under 1000.
