We most likely have a problem with the number 8 ignition coil. This is the rear cool on the left side of the engine. Remove the six 7mm bolts holding the ciol cover then remove the bolts for the coil. Inspect for any oil or water on the coil. Swap it with another cylinder and clear the fault code to see if it travels with the coil. Let me know.
