if i dont have time to take it right ,will it effect anything or cause more problems,and could this be the reason i have really bad gas milage?

I wouldnt wait too long, you may smell fumes if the vent is stuck open...

Where is this part located and can I replacement it
myself.

Yes you can. It is located close to fuel tank. When purchase a new one you will know what to look for. There is a quick connect hose you will have to disconnect and one electrical connector. The hose goes to the EVAP canister which is also mounted close to the fuel tank. I work at a chevy dealership. Let me know if you have any questions.

I just learned that my EVAP Vent Solenoid needs to be replaced, am looking for a quick walk through on how to change it out. Thanks.

Hello,

The EVAP canister is under the truck on the drivers side near the rear. Here are diagrams to help you see what you are in for when doing the job. Step by step instructions.

How do i fix the emissions vent valve?

Check with your local GM dealer. There is an updated parts kit . The valve gets replaced and the filter gets located above the transmission. They should have a copy of a service bulletin for this.
