I'm having trouble with my Idle Air Control Valve. When I stop my engine will quickly drop its idle speed then pick back up. I know this because I can hear it as well as all of my lights get dimmer for a second. The problem got worse once it got cold. And occasionally it will stall at light/stop signs. I finally got fed up with it and cleaned the IACV with electrical parts cleaner. It was fine for a day or so then started acting up again. So I got a new one from AutoZone. Guess my question is do you all trust the brand Duralast?
