xb9sx runs rough after fill up

Haha, the airbox base has been off for 2 days now. I've been checking for and chafed wires and tightened the big ground wire . Hopefully when I get home today it will either throw the same code and die or run fine.

So far it has been:
O2 sensor
Fuel pump ground
TPS sensor too low

I can't imagine it is all these things at the same time so Im thinking it is electrical related.

pure unadulterated classic low voltage condition AND poor grounds. hence the fault codes.

Just an update.

Since reseating the ECM and tightening down on all the grounds and battery terminals, and performing a properly warmed up TPS reset, I have put 200 issue free miles on the bike. Thank you for all the suggestions.
