[QUOTE="918evo, post: 2738210, member: 6001"] If it ran great and then all of a sudden started to shake at idle, and lack power, with that code, my money is on a bad coil. It is easy to diagnose if you have some hand tools and a little know-how. Cylinder 3 should be the rear middle one, so I would unplug it and see if the engine runs the same or worse. If it runs the same, then remove the coil and change it with another coil from a different cylinder, and repeat and see if the misfire moves from cylinder 3 to a different cylinder. A coil is around $100 with tax, so expect to pay $200 to have someone fair do it. [/QUOTE]
