Yesterday I had to remove the air filter unit to change out the serpentine belt in my C6Z. I started the car up and noticed that I forgot to connect the vacuum line on the side of the air bridge. I turned the car off and reconnected the vacuum line. Now today the car has a steady check engine light. How do you reset this light? I tried doing the c5 trick where you hold down the options button while hitting the fuel button 4 times. It doesn't work. I'm pretty sure this is what is causing the light to turn on. Yes, I checked to see if the gas cap was tight. Anyone?
