Just because it runs better under hard acceleration is no indicator that the plugs/wires/coils are ok. I would try swapping all three (one at a time, plug first, then wire, then coil) to see if the miss moves with the component. If it stays at #2, you can eliminate the above parts as the cause of the miss. This leaves you with either a bad ignition module (they will fail due to heat and can fail on only one cylinder), or a fuel/compression issue. These are harder to test because they require special tools (DMM, noid light set and compression guage) but not technically difficult. The ignition module can be tested for free at Advance and Auto-Zone, but if it's cooled off when they test it, it may not detect the problem. Try the simple things first, and let us know if swapping the ignition components helped.
