CB1100 Idle speed instability problem

[dave]

Ferret: Thank you so much for doing this! All of us with idle issues thank you. Curlyjoe, thank you for creating the spreadsheet - I will edit it right after I complete this post.

I am willing to bet that some of the cures, such as bad gas, TPS reset, and replacing the battery are not permanent. My issue comes and goes as it pleases. Is there a way we can include on the spread sheet if the "cure" was permanent or not?

I did not see the post from Beardy about the different part number on the IACV - this is very interesting! The throttle body assemblies are the same part number for both years, so this means the new IACV can be installed in the earlier models. However, the PGM-FI Units have different part numbers, so I am not sure if the different part number IACV would work or not. However, I would really like to know why Honda changed the part number for the IACV. I am the one who posted that the CB1100 IACV part number is used on many different Honda motorcycles - why suddenly change it?

Thanks again to Ferret and Curlyjoe for help resolving this annoying issue. This is exactly why I love this forum - people are so willing to help.
