Hondata

driving down the road... check engine light pops up... car runs really rich.. pull over, turn the car off.. give the ecu a little shake... turn the car back on.. the light dissappears... car runs perfectly normal... something's loose? tuner says hondata's loosing connection with ecu somehow? checked pins outside and they're ok... is this an easy fix?

It will be the socketing. Go over the socketing again and check that there are no lifted tracks, shorted connections or bad solder joints. If you can, post photos of the soldering here.
