Get an injector buzz test done. Then you will know which injector(s) have issues.
A bad IPR can cause an idle miss as well. You did the first part, which was unplugging the ICP sensor and if it does the same thing still, it usually indicates a bad IPR.
However, I recommend the injector buzz test to make sure all of your injectors are functioning properly. If you have keen hearing, you might be able to stick your head in the wheel well and listen to the injectors and a sticking injector is usually quite obvious.
edit: If it's an injector going bad, chances are it's the #8. Driver's side, rear-most injector is the #8.
