For some reason when ever i turn my car on after its been sitting for more than 15 minutes it lets out a realy high pitch screech. I posted on the mdpreludeclub forums and they said that i could be becasue my belts might be old and need replaced or they need to be tightened. Does anyone else know what the problem could be?

 

yeah - check your belts.

 

yeah i had same problem...tighten your belts, or if needed replace worn ones.
