I have a 2005 dodge Caravan 3.3 engine with 55,000 miles . Engine light came on , auto zone read codes as 403 and 404. Which is EGR faults. they have no parts available in the EGR circuit. Vehicle runs great can't see anything wrong with performance. I had them clear but came back on in about an hour. Where should I start checking without swapping expensive dealer parts ?. There is no dealers in area that I can trust. The chilton book doesn't give much info on the EGR and trouble shooting.
