resetting obd1
Now by reset do u mean clear the codes and the learned fuel curve? (If that applies to the v-6 cars) do u have ur owners manual? There's a fuse that is for the ecm, pull it for a few moments, or disconnect your + battery cable for 5-10 mins. Now if u mean u had the ecm tuned, don't know if they can do that on a 93, I think a 93 is an eprom, and any tunning would be done via a chip that's connected to the ecm. But incase I'm wrong, if u had the ecm tuned and it was more than a flash tuning, it would have to have the stock programing put back on it. I may be wrong, as far as the eprom, but I don't think I am. Easiest way is pull the fuse, owners manual will tell u which fuse. Hope this helps.
Sorry, I'll learn to read one day, a 94 is not an eprom. As such pull the fuse or disconnect the + batt cable. Same goes for the ecm if u sent it off for programing. Would have to have stock tuning re installed.
