The gap should be 25 thousandths. .025. Many times there is a factory sticker under the hood with that information.

One reason a 1998 Cadillac Deville would cut off while driving could be the fuel pump or the car is out of fuel. Another reason could be the spark plugs.
Spark plugs are easy to change. One disconnects the batter and spark plug cables, and removes the old spark plugs. Next a person puts in the new spark plugs, then reconnects spark plug cables and the battery.

The 5.7 in your Cadillac is a Chevrolet LT1. The same motor that came in an Impala SS and Buick Roadmaster. It uses an "OPTI SPARK" distributor that runs off the front of the motor. There is no timing adjustment that can be made with the unit. The engine management computer controls the timing and adjusts the spark as ou drive. If you are having timing problems, the OPTI SPARK needs to be replaced.
NO! Just check the spark plugs; the fuel pump.
A spark plug, tork is something that sparks to run but the torque gives it extra power because it is a cadillac
it could be numerous things. spark plugs, fuel injectors, burnt valves, distributor, plug wires .... its hard to tell with out hooking it up to a diagnostic tool.
I have a 97 Mirage LS Coupe and the spark pluge are located under the coil wires. If you are looking at your motor from the front of the car you can get to the 4 plugs on the top of the motor. You will need a 10mm socket to remove the coil wires. There are 2 of them. There are near the oil cap. I hope that helps.
Were the spark plugs oil fouled? If so it can be a valve cover gasket, oil would be leaking into your spark plugs.
