I went to Courtesy Ford in East Portland the last time my CEL was on. Turned out to be a mis-fire on plug 5. They wanted to charge a mint for the tune-up as well as a fuel injector service! I declined and tuned it up myself. That's when I was hunting for the 9mm wires. I picked those up at some speed shop off of I-84 and got the Motorcraft Double Platinum plugs here in Vancouver. Runs very well! At any rate, the guys over at Courtesy were polite. I would take my car there for major service.
