Greetings all after 4 years my Diane’s 2004 basic Vibe with 19k has developed a problem.The check engine light came on I canceled it a week ago by removing the negative battery terminal then it returned this time I hooked up a portable diagnostic tool and received a P0037 code error, but where do I begin to fix this problem or is it something that must be done by the dealer?The code references came from this link http://cyberviber.googlepages....s.pdf She did say that the heater smelled like something was burning I cant verify that though, I have noticed it doesn’t have much pep.Does anyone have advice for me?
