Hi Marcel,
I cleaned the IAT sensor with electrical contact cleaner and let it dry before reconnecting it.
I also cleaned all connectors I could get my hand on with electrical contact cleaner and let them dry overnight.
All critical connectors have been waterproofed with mastic tape and electrical tape, all secured in place with plastic cable ties to keep out moisture.
It’s been over two weeks now and the bike seems to have fully recovered. It’s the longest uninterrupted riding in recent memory.
Thank You!
