Check engine lights involve the engine's electronics and/or electrical system, since they are interrelated. My '97 Sable's recent check engine light signified a problem with the camshaft sensor, which had to be replaced. Important, since it works with the ignition system, and while AAA is good to have, I hate being towed. It's a tricky repair, and like most manufacturers, Ford has the system designed to mandate a particular repair tool that's expensive to buy. The job's a pain anyway, and can be tricky, so it's best to have a certified mechanic you trust do it (I do not, repeat, do not, like dealerships for a variety of reasons). Never ignore a check engine light; generally easy to computer diagnose (but prepare to pay for an hour of diagnostics). All dash lights are potentially bogus -- sometimes these things take on a life of their own, signifying nothing, but it's foolhardy to assume that. Hope this helps.
