Have the capacitors been replaced on the ECU?

The capacitors are over 25 years old and any of them could be leading or dying. I would highly recommend replacing them and see if this resolves the issue.

Q31 was damaged from swapping the purge and IAT sensor plugs. Does it connect now that the capacitors have been replaced?
