Thanks for the reply. It's on a 2000 V6 Firebird, the car was scanned at Autozone. The car does have a little trouble starting??

I'm thinking they got the code wrong somehow, couldn't find it thumbing through my helms DTC list either. If the light is still on or stored in history I'd bring it somewhere else and have it read again. Maybe it's a P03XX code.

Well the first guy was a dumb ***.....here's the code from the second scan..

The first code is P1441
Definition: EVAP System Flow During Non-Purge Condition
Explanation: The ECM has detected vacuum flow to the Fuel Tank
Pressure (FTP) sensor during a system sealed condition
Probably Causes: 1. Failed canister purge solenoid
2. Failed Fuel Tank Pressure (FTP) sensor

The second code is P0446
Definion: EVAP (Evaporative Emission System) purge/vent solenoid circuit condition
Explanation: The solenoids and system wiring are monitored for opens or shorts
Probable Causes: 1. Purge or vent solenoids defective
2. Check connector and wiring
3. Fuel saturated vapor canister
4. Failed EVAP vent solenoid
