Do yourself a big favor and go buy a code reader. You can get a decent one for about 60 bucks at someplace like Sears. That's about 1/2 hr. labor at your local Ford Stealership. You will use it again after this, I guarantee it. Then you go online and research your codes, fix the problem(s), erase the codes and you're back truckin with a smile of satisfaction on your mug!
