Review on 🔍 Dorman 911-035 Vapor Canister Purge Valve for Compatible Models by Victor Ceja

I was clueless enough to believe that this new one only works because it holds a vacuum. I feel like I still have an issue with my general emissions trouble code P0440. Yesterday I decided to check if the vacuum is off and working, but the device is not working and the valve opened. I ended up putting the old one back in. What I don't know yet is if they make noise and pulsate or are only open when the machine is running or in a cycle. Since I bought this part last fall and have parked the car unused for so long, it's too late to return it. I didn't buy a guarantee.
