1993 Cadillac Eldorado 4.9L Random Data Errors
Ok, total noob but I thought I might ask before pulling the rest of my hair out. The car has an onboard interface and I get good data from it but when I try to get data from the ALDL plug it is totally random. The data changes several times a second and it is total non-sense, even the EPROM Serial. My battery voltage goes from .247 to 78465736.2 yet the dash says it it a steady 13.9v. Any thoughts? The car runs well and isn't throwing codes except the very occasional ICS motor mismatch which is a non-issue. I tried two different computers and a smartphone and it isn't on the software end.
