double check the solder joints on the caps. A bad solder job will possibly cause issues as the ecu, and the case and the board, and the components, and all the other things involved shrink at different rates due to the temp.
Double check for a grey color at the joints they should also be smooth and have flowed onto the board. If they are lumpy and/or shiny redo them they are probabally no good.
Also, check to make sure none of the traces around the caps were damaged during the replacement. A small scratch in a trace may seperate when it gets cold.
As for why anyone would change the caps themself, I fixed my ecu with bad caps for 4 bucks. If anyone would like I will change theirs for 175.00 and even throw in free shipping. I used the 171.00 leftover to buy my wife a present so that I can spend more on the toys.
Its always a good idea not to bite the hand that can make your life miserable.
Hope to help had the same issue now it is fixed.
