I have a 1999 cougar v6 that my reg mechanic gave up on. can't get engine light to stay off. supposedely egr related. replaced all related hardware code still gets generated. can't pass inspection. at this point it might have been cheaper to buy another car. if you have an idea or know a wizard cougar tech in the fort worth tx area please respond. car has over 150k on it.
thanks,
