Guys, I have an 01' 2wd ST, with 116,968 miles, and my OD light came on on a Saturday morning just as I was about to drive it! I had just finished figuring out where the horn fuses were and how to check the horn, and cranked it up to drive out and there was the dreaded flashing of the light! Out of curiosity, I drove it about a hundred feet in the parking lot and it had some hesitation and slowness to it so I parked it asap and went on this site to find some owner info on that issue. From this site I found that it was not a good thing to see. Hopefully it won't cost a mint. Good thing is that Ford Credit is going to defer a couple of payments to help the fix! (Maybe they know the scoop on this issue!)
