By the way, I forgot to mention that it is a 5.4 Triton V8. Its been a good engine thus far...for the time i've had it anyway. I am a college student and work at Sears for money. I went to the auto department and asked how bad the spark plugs were to get at. They told me its atleast a 3 hour job for a professional. Then they told me if i felt like doing it myself, I could expect more time yet. They do look a little tricky...
