Well here I am, I just got my 2003 Windstar back from the dealer. The CEL came on, so I called and made an appointment. They called to say that the code 0171 & 00174 came up. That I have "clogged EGR ports". She then said it would just bee $572.98 to fix it...requiring replacing 6 O ring gaskets, insulator bolts, etc. I can't affort that, so I picked it up. I called another dealer, who referred me to a mechanic at a Lincoln Mercury Dealer. He asked how many miles are on it. It has 70,000 miles, runs great, and has had the routine oil changes, just as recommended by Ford. He told me that he would be more likely to belive it if it had 200,000 miles on it. So, my question is what you guys think, and is there an alternative way to clean them out. I have seen other less costly solutions on the web with other vehicles. Please help me with any suggestions you may have. Here in Florida, we do not have emissions inspections, so unless the CEL light came on, I wouldn't have known anything about it. $80.00 spent so far. By the way, the CEL is not on, if they have reset it, how long until it comes on again, and am I causing problems by driving it? We are about to have company and plan to use the van for trips of about 40 miles at the most.Thanks!
