More of a generic question, but it would help me decide if I want to let Ford have at my Taurus, or just drive it to the damn scrap yard and get this over with.
I have an OBD1 scanner (93 taurus) and in the past, it has given me a few codes that have helped with problems so I know it works, and I guess I can say that I know how to run the tests. At the moment, with my high engine speed problem, it shows no codes at all.
All I have to go on with this statement, is that it is what folks have told me, and that statement is that Ford dealer scanners can access codes that are not revealed by the $100 scanner that I am using. I have heard yes and no, but some are adamant that they can retrieve information that I cannot.
As it is, I have no codes to go on. If Ford can dig out more, and useful ones, then maybe I have to bite the bullet, but if I am going to pay them $100 just to read the computer and come up with no codes, that doesn't seem like the right way to go.
Anyone have any insight or comments? Are there "hidden codes" in the OBD1 computer that only Ford can view?
Thanks,
John
