This chirp is present at start, idle and throttle. It only stops after the car has been running for about 30 minutes.... sometimes.
I had a similar situation recently. Replaced everything in the belt tensioning system - belt, shock, spring, tensioner arm, tensioner pulley, etc. - didn't fix the problem. Belt chirp & squeal that only happened when car was first started and first few minutes of driving, but went away once engine was warmed up. Here's my thread: 606 crank pulley? See post #6 from Murkybenz, he was right on the money.

The problem on my car was the water pump. Water pump bearings had gone bad, causing drag on the pulley and squeals and chirps from the belt. When I replaced the water pump, I found it was the almost twenty year old original from 1998. As soon as I replaced the water pump, the noise was completely gone!
