My car has developed a misfire when started from cold. I haven't driven it for any length of time since this fault has developed so I don't know if it will disappear once warm. I've decided to remove and replace the capacitors in the ECU as part of my fault finding mission.

Pictured is my ECU. All the caps look in good condition and there are no signs of corrosion but I'm going to swap the vulnerable ones whilst I have access to them. Some of the caps look to have been marked, do we think that they have been replaced already or was this factory standard?

If this doesn't cure the problem what next people?

Major service done approx 3 years ago. Oil is in great condition. Done approx 5k in those three years.
