Where are the spark plugs on a 1991 Dodge Stealth?

The spark plugs on a 1991 Dodge Stealth are located on the top of the engine, under the plastic engine covers. Because it depends on the engine (3.0L V6 or the turbocharged 2.6L V6), a more precise location isn't possible without knowing the specific engine. However, they're generally accessible after removing the top engine cover(s). You'll likely need a socket wrench and possibly a spark plug socket extension to reach them easily. Consult a repair manual specific to your Stealth's engine for diagrams and precise locations.
