When I start it in the morning I get several messages which include Stop Engine, AC Compressor Off, Engine Overheated, etc. This goes on for about 5 minutes and then everything runs normally. I've been told it is the computer. Which one? can anybody tell me what to replace or do? About 6 months ago the transmission shift solenoids were replaced.

You might want to post this up in Seville/Eldorado or have a Moderator move it - you have some Diagnostic Trouble Codes (DTC). Read the entire sticky thread at the top of the main Seville/Eldorado page titled "How to pull codes", write any codes found down and return to the sticky and open the URL with "obd1" in the address. Click on the lines in the Master Index box to get the meaning of any P,B,C, or U codes.
