Ask your mechanic to run a compression test. The readings between the different cylinder should be quite close.

Is you car consuming engine lubricants? What about the coolant? Do you see any "milk" like residue on the inside of your rad. cap? Any overheating lately?

 

[flash]

ECU? Suffered misfiring on 1 cylinder once. Moved the coils around, still the same cylinder having misfiring. Did the same with the cable. Still the same cylinder misfiring. Replaced the ECU, back to normal.
