CB1100 Idle speed instability problem

[peterbaron]

Well well well; hello everyone! I have good news (at least in my case).  Like many others, I was having idle problems and bike shutting off when stopped at a light or while riding.  After reading all the discussions here, I decided to change the iacv myself without ant troubleshooting(I know its crazy but didnt want yo spend hours troubleshooting). So I boight the part and with the help Ingot my hands on a service manual.  So I took apart the seat, tank, left and right covers; the rear air filter housing and for the life of me, I couldnot remove front air filter housing that is attached to throttle control. In the effort to do all these, I had disconnected the battery and most harnesses including the computer.  So I decided to put everything back and accept defete and take the bike to a shop for repairs.  I put everything back
and to my surprise the bike was fixed by just disconnecting all the parts and letting it sit for a few days... guys; if you have the same issue; try this; it may help!

By disconnecting the battery/ECU for an extended period, you inadvertenly reset all the resudial values in the ECU, but is almost certain that the problem will return ???...
