[QUOTE="Richard L, post: 906988, member: 52972"] Engine noises are nearly impossible to diagnose without being able to hear them. What you describe as a "Swooping" sound, someone else might describe as a "Roaring" sound?? Since it goies away quickly it's probably nothing to worry about. As for the "Chirping" sound, my guess is that you may have a bad idler/tension pully. That has been a common problem with the Sport Trac engines with the serpentine belts. it may not be source of the chirping, but if it is bad it can cause belt misalignment wihich can cause the chiping to come from the belt rubbing on the pulleys of nearby components. ...Rich [/QUOTE]
