[QUOTE="Rick Ohnsman, post: 908077, member: 66408"] My '03 ST is in the shop today. The truck suddenly lost power and could only get to 40 mph regardless of how much gas I gave it. It also had a rough idle and smelled bad, kind of like it was running way too rich. I thought maybe a bad O2 sensor. I limped it home and the next day, when I started it up and drove it to the dealer, it of course ran fine. The dealer mechanic could not find anything in particular wrong with it and, since the check engine light did not come on, there were no codes as a clue. They've done several things, a general tune-up, plugs replacement, and a new one to me - they are "flashing the computer." Wazzat? Has anyone heard of this procedure and what might it do to fix the problem?? [/QUOTE]
