What is spark plug firing rotation for 1993 grand prix Pontiac?

The firing order for a 1993 Pontiac Grand Prix depends on the engine it has. There were several engine options available that year. You must know your engine's displacement (e.g., 3.1L, 3.4L, 3.8L) to determine the correct firing order.

Once you know the engine size, you can find the firing order in your owner's manual or online through a reliable automotive repair resource like a Haynes or Chilton manual specific to your year and model Grand Prix. Searching online for "[Your Engine Size] Pontiac Grand Prix Firing Order" should also yield results.

Without knowing the engine size, I cannot provide the correct firing order.
