I have a 1999 Dodge Intrepid with 90,000 mile and it has a loud low pitch noise in the engine immediatelly off idle. It sounds like an idler pulley bearing, but I've checked the engine noise with the accessory belt off and it stll makes a noise. I've also checked the water pump and timing belt idler pulley bearings and they are OK. I also removed the harmonic balancer with the engine running and it still made the noise.

You hear a high-pitched squeal that stops when you shut off your engine: Readjust or replace the belt. These belts should have about half an inch of play and ...Missing: 1999 plymouth breeze
Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one
check your power steering fluid and pump, also these units have a problem with the rack and pinion unit, but start at the power steering fluid resovior and look for leaks, low fluid will cause the pump to starve for fluid cause irrepairable damage and noise as well... please rate my help, thanks
I had the same problem on my 2005 Envoy. Turned out to be the idler pulley bearing. It is just a pulley the belt rides on. The bearing in the pulley was what was making the high pitched whine. I replaced the bearing, and the noise went away.
Which engine is it?
