Hey everyone, i don't know if this was posted at one time before or not i didn't read too far into it. I live in ohio and i parked my car for winter but i have started it once every two weeks or so. It was parked for a total of about eight weeks and the car i was driving for winter was having some transmission problems so i had to drive the cobalt. My factory boost gauge lights up but doesn't move and i am still getting boost. What is going on and it what should i do? All help is thankful!
