2007 Chevy impala that has been idling rough for about a month and this
morning i have no heat from the dash. the car is not over heating or having
any other apparent mechanical issues. any easy fix i can check my self, or do
i take it in and have it checked for a blown head gasket.
Try cleaning the throttle body https://www.youtube.com/watch?v=zUV4nXc-pXU
