I have a nice 88 coupe deville and from this forum just learned how to retrieve codes from the info center. These are the codes that came up in order: E28, F46, F47, Also while doing this the service eng soon and the check eng lites came on. Can anyone tell me what the codes mean? Thanks.

Its amazing what a little research on this computer will turn up. I was able to find out what the codes are, however on one of them the code read: open fourth gear circuit. Can anyone tell me what that means and how do I go about correcting it?

You mean to tell me with all of you so called cadillac experts out here no one can tell me what an open forth gear circuit means. I thought this forum was put in place for us to help each other. I'm sure theres someone out here that can assist me.
