How do you clean the ICV? I have mine removed at the moment.

I can't say if it helped or not since as it turned out, the engine had far greater issues than metering air flow. Considering the ease of cleaning, I'd go ahead and clean it. Have a look at your ICV as well. That valve can have a big impact on idle. HTH
