CB1100 Idle speed instability problem

[Magnus_imp]

Yes, I had the Guhl reflash and several thousand miles later developed a constant high idle (1500rpm) problem. I've never had a low idle or stalling problem. The high idle problem persisted for about six months during which time I tried replacing the Idle Air Control Value (IACV) and the Engine Operating Temp sensor (EOT?) to no avail. Then about a month ago out of nowhere it fixed itself and has been perfect since... go figure.

I would be very very surprised is a Guhl reflash would make any difference one way or another with idle.
