service engine soon light
I have a 2001 f150 4.2L V6, I just turned 130000 miles on it, and the service engine soon light just came on, the truck runs great, and I just replaced the alternater, anyone have any idea what the problem could be?

You need to get the OBD2 codes read. Most parts stores will read them at no charge, post back with the exact "P" numbers. If you have to, you can buy your own code scanner for less than 50 bucks.
