The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
I don't see why not. You'll probobly have to switch all the accessories for it too but The deville hasn't really changed very much since 1994 in fact in 94 it came with the option of the 4.9 and the 4.6 Northtar that comes standard in the 01.
you have a problem with theft system possible key cylinder
Buy a kit at Wal-Mart or auto parts comes with instructions
My 01 deville had a cracked intake boot, between the throttle body and intake manifold, it would only leak when eng was hot.
96 cadillac deville leaking on driver side bottom wondering what it could be from...... As long as it's not emptying, it's common that coolant comes out the over flow due to being over full

The check engine light comes on at start up for a bulb check. If it stays on with the engine running the computer has detected a malfunction. You need to have it checked for codes.
