To remove the stuck spark plugs, you can break them loose and then start to get them tighter as you rotate them out. The ratchet wrench can also be used to remove the stuck spark plugs.
Remove the fuel tank, Remove air box, Remove spark plug caps, Remove spark plugs ????
Pull the spark plug wires off the spark plugs. Remove the spark plugs with a spark plug socket. Install the new spark plugs and put the spark plug wires back on. I recomend replacing the spark plug wires as well. If replacing them, just remember that the new wires are hooked up the same ways that the old ones came off.
The 1991 Cutlass Cierra came standard with a 4 cylinder engine. This would require 4 spark plugs to tune up the engine.
Disconnect the battery, remove the engine cover, remove the spark plugs wires and boots, and remove the spark plugs. Put in the new spark plugs, replace the spark plug wires and boots, replace the engine cover, and connect the battery.
You do not need to remove the fuel rail to remove the spark plugs.
Remove old spark plugs. Insert new spark plugs..... Simples
