A 1993 Chevy what? The location of spark plugs varies significantly depending on the *engine* in your 1993 Chevy. Chevy made many different models and engines in 1993 (Camaro, Cavalier, Silverado, etc., each with multiple engine options).
To tell you where the spark plugs are, I need to know the engine size and model. (e.g., "3.1L V6," "4.3L V6," "5.7L V8," etc.). This information is usually found on a sticker under the hood or in your owner's manual.
