X Roadie Posted July 15, 2011 Share Posted July 15, 2011 My VSC and check engine light just came on. I check the gas cap, it is ok, I checked the hose behind the air filter and reattach it to ensure it was on correctly then disconnected neg lead to battery . Unfortunately it did t work for me. Is there anything else I can do or any other suggestions Quote Link to comment Share on other sites More sharing options...
