If you changed the spark plugs in your 1993 Lincoln Mark VIII from Autolite 764s to SP493 Platinum Stars and the car is now running rough, there are a few possible explanations.
The new spark plugs may not be gapped correctly. The gap on a spark plug is the distance between the center electrode and the ground electrode. If the gap is too wide or too narrow, the spark plug will not fire properly.
The new spark plugs may not be compatible with your car's engine. Some cars require specific spark plugs, and if you use the wrong plugs, the car may not run properly.
The new spark plugs may not be seated properly in the engine. If the spark plugs are not seated properly, they will not be able to make a good connection with the engine, and the car will not run properly.
If you are sure that the spark plugs are gapped correctly and are compatible with your car's engine, and they are seated properly, then the most likely explanation is that the new spark plugs are simply not providing enough spark. This could be due to a number of factors, such as the quality of the spark plugs, the condition of the engine, or the type of fuel being used.
If you are still having trouble with your car after changing the spark plugs, you should take it to a qualified mechanic to have them diagnose the problem.
