service engine soon light
My '99 Lariat with the 5.4L did exactly the same thing at around 63,000 miles. Took it to the Ford dealer and discovered that I had a bad Oxygen sensor. It was a little pricey to have replaced, but since I was going to have to pay for the diagnostic if I didn't let them do it, I went along for the ride. The bill for diagnostic and labor to replace the sensor was $137 and the O2 sensor itself was about $90. For what it's worth, it was the passenger side sensor that was bad.

On a 99? Didn't your warranty cover it? or did yuo have the 3 year/36,000 mile warranty? I really hate how stuff starts to go after the warranty is up, on anything you buy, not just cars. It's with TV's, CD players, Toasters, everything, you name it buddy!! I say everyone in America puts their fists down and says "hell no, this stinks like rotten meat!" Lol, well, I doubt that'll happen, so I guess we'll just continue to pay more for things, and have limited warrantees, yada yada....hehe.

THe "check engine light" usually comes on due to a emmission related problem, bad Oxy. sensor, cam position sensor, etc... years back, these items were covered for 5 and 50,000 , but now it's only 3 and 36,000 as per the Feds relaxing standards. The computer will store a code as to what's acting up. It may not bother you again for a while, but may come back on again at a later date. The dealer or someone with the right diag tools has to clear this code out of the comp.
