I tried replacing the tensioner without avail... however, I got a little closer and noticed it was coming from the A/C belt line... on the A/C Idler pulley... picked one up from GM and the squeak has never come back since. See if you can tell if its coming from down low, and its most likely the a/c idler down by the crank.

Accessory Drive Belt - Squeak/Chirp Noise
BULLETIN NUMBER: 00-06-01-008
DATE: March 2000
SUBJECT: Accessory Drive Belt Squeak/Chirp Noise (Install New Double Row Idler Pulley, Generator Bracket and Serpentine Belt)
MODELS:
1998-2000 Chevrolet Camaro
1998-2000 Pontiac Firebird
Built Prior to VIN Breakpoint Y2107225 with 5.7L V8 Engine (VIN G - RPO LS1)
CONDITION: Some customers may comment on a squeak/chirp noise coming from the accessory drive serpentine belt. The noise will be most noticeable at idle and low engine speeds.
CAUSE: The serpentine belt squeak/chirp noise may be caused by misalignment between the idler pulley and crankshaft pulley. A slight rocking motion of the idler pulley causes the misalignment, which results in noise.
CORRECTION: To correct this condition on vehicles built prior to the above VIN breakpoint, install the new generator bracket, double row idler pulley and serpentine belt following Service Manual procedures.
Important: The new generator bracket can be identified by the depth of the idler pulley mounting pilot. The pilot dimension (2) on the new generator bracket is 10 mm. Dimension (2) on the previous bracket was 8.3 mm.
