From memory the 10uF on the large board is right next to the transistors that switch the idle control valve. I would therefore suspect it is in as decoupling for these surges, and will mean it is seeing transients of 1 - 2 A, way outside normal rating for a 10u Electrolytic.As above, I will probably be changing to surface mount ceramic instead for future repairs. Back when these ecu's were designed, a 10u ceramic was a large item, now they're down to 0603 and I think even 0402 size (AKA microscope tiddlywinks).
