    Possibly the injector. Before buying a new one I would try to clean the current one. I often hear about people replacing coil, spark plug, and plug wires when it turns out all along it was the injector. Try swapping a coil, plug and wire from a known working cylinder and see if you still get the same code. If so it is likely the injector. Anybody else have any thoughts.

    Had a buddy have the same issue with a misfire in a Chevy Pick Up. A mechanic friend of his told him it could be one of a dozen things. I told him to throw a bottle of injector cleaner in the tank. Ran the truck for 15 minutes. And the misfire stopped. Start with the cheapest easiest fix. And go from there.

    I would also follow the advice of OFFGRID. Peter knows his s--t. :bowdown:
