They have been able to determine that Cylinder #2 is misfiring. They are not sure why yet. They got it to act up a lot today on the road but they can’t reproduce it in the shop. They don’t have a dyno that the car can be “driven” on in the shop. The current theory is that its either the coil or the ignition module. They are leaning towards the coil. The plugs and wires look good. The investigation will continue into tomorrow at least.
