Cold start noise

My 1998 Continental makes a noise during cold starts that sounds somewhat like the starter is not disengaging. The noise lasts a few seconds longer the colder the outside temperature is then disappears unless engine is revved. The noise completely disappears once the engine is warmed up. Thinking it was a starter issue I put a new one on, but it didn't change anything. Then took it to a local mechanic who I trust and also the Lincoln dealer. Both thought it was a vibration (resonance) coming from the power steering line (apparently there is a TSB out about this) and both said the cost to fix it wasn't worth the money unless I couldn't stand the noise.
Has anyone else experienced this? Is there anything else I should consider?
Thanks for any insight you can give.

The sound you are hearing does it sound kinda like a squeel?It could be a loose or worn belt.Possibly a bad bearing on your power steering pump or altinator maybe.The best advise i can give is to check all the simple easy to fix things first.

Typical Low-Speed Vibrations (Less Than 72 km/h [45 mph]):

exhaust vibration
engine harshness/vibration
power steering pump vibrations
drive belt vibrations
engine cooling fan vibration
take-off shudder (excessive CV joint operating angles or bad CV joint)
brake roughness or harshness
driveline roughness
excessive wheel runout
tire flat spots
components/material trapped between the body and the frame, the engine and the frame or the engine and the body
automatic transaxle clutch slippageTypical High-Speed Vibrations (Above 72 km/h [45 mph]):

excessive tire-wheel and brake disc imbalance
tire roughness due to high non-uniformity (force variation) or out-of-balance condition
excessive tire and wheel runout
components/material trapped between the body and the frame, the engine and the frame, or the engine and the body
worn suspension components
front end accessory vibrations
exhaust vibration
