Yes any Ford Lincoln mercury dealership can look at it. I just took my wife's in and they tried and tried and couldn't get it figured out. Finally we got another rep at the same dealer and they found it immediately. It was 4 and 7 on our car and it would dang near shut down the dash.
Her milage was around 13 MPG before and now it is back up to 15~16. Tell them to keep looking at the coil packs. We also ran two bottles of Techron injector cleaner as well.
