Contour Enthusiasts Group Archives Forums General Troubleshooting Loud Humming noise or horn like sound?

I have only noticed this sound coming from my car since the winter has begun. After a cold start up, my car (2000 SVT) makes this very loud Horn like sound (only of course its not my horn) coming from underneath my car. Usually when I engage first or stay in third or something but keep it in the same rpm range for a second. The sound is at first loud but then kind of just fades out or dies out until the next cold start up. Any feed back. Thanks very much all. Also, car was not affected by previous winters.

Moose strikes again!

You can do a search for Moose to see opinions, or go to the FAQ for throttle hang.

My opinion is to clean the UIM, TB, MAF, and IAC first.

i didn't know what the moose was all about until this winter and after i installed my SVT UIM this past summer. Its pissing me off because i know what it is but its too cold to work outside on the car, or maybe because i'm too lazy.
the same problem as you described it. try this http://contour.org/FAQ/FAQ.php?s=probs&displayid=15
