The vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I am not aware of any aftermarket parts suppliers.

hi this could be a lot of things, the only way to find out is to have it checked with a code reader, it could be something simple like a miss fire as sometimes happens or could be something more serious best get it checked out, you could have a sensor gone u/s and you might be using allot of fuel.....hope this helps

2006 Chevrolet Colorado LT 2.8L, Vin 8, Eng Cfg L4 Customer Concern: Current Powertrain Control Module (PCM) code P0449. Tests/Procedures: 1. Inspect the evaporative vent solenoid, near the fuel tank and evaporative canister. Look for wire damage, corrosion.
2. Check voltage to the solenoid on the Orange wire. It should be battery voltage, backprobing. If not, check the voltage level on the CAN VENT fuse, #69 in the Underhood Bussed Electrical Center (UBEC).
3. Cycle the evaporative vent solenoid with a scan tool. The solenoid should click.
4. Backprobe the White wire, pin 22 of the blue PCM connector. The voltage on this wire should be battery voltage with the solenoid off and close to 0 volts with the solenoid on. Potential Causes: Evaporative Vent Solenoid
Tech Tips: The evaporative vent solenoid is attached to the side of the evaporative canister above the spare tire.
