IIE321 Posted February 10, 2012 Share Posted February 10, 2012 Hello, My check engine and VSC light keeps on coming on and off. It has been happening since October 2011. I checked my gas cap - and it is tight. Any leads on what I should do? The check engine report states that the knock sensors may be a problem. Please help! Thank you.
