I have an 89 LS coupe that I recently purchased. Sometimes the information center says that I need to check my oil level even though it's full. What could be causing it? I changed the oil a few days ago. The info center also reads n/a on the distance to empty for the fuel and the coolant level. Is there some sort of short in the system or is this common and how do I fix it?<br><br>Thanks!!<br><br>Bobby
