Hey Elky,
Here is what I got from the Massachusetts site:
"Extended Emissions Warranties. Vehicles sold in Massachusetts after 1995 carry "California certified" warranties, which cover any defective part for three years/50,000 miles and "high priced" parts for seven years/70,000 miles (in addition to the usual warranty the manufacturer provides). The cost for a "high priced" part is $440 and over. These include items such as the catalyst and the OBD computer itself. Vehicles from out of state may be covered by the more limited "federally certified" warranties, which cover all parts for two years/24,000 miles, and only the catalytic converter and OBD system for eight years/80,000 miles. NOTE: you should check your warranty information carefully since you may have other warranties in addition to those mentioned here."

I am calling my old stealership in Westboro now to see what they say about it but if you have any info on a shop that will do the work it would be appreciated...the stealership that told me that was Waltham Ford...thanks
Also I was told that my car had california emissions...Duddie Ford told me that if 5E212, 5G218, or 5F250 was in the middle of the part number then I should be covered for 7yrs/70K miles....I am calling Waltham to get part numbers and then Duddie wants me to call them back..I will update with info
