There has to be a VERY close fit around the throttle plate. Any stray air leakage and your idle will remain high. I had that problem when I first bored mine.

That goes for ANY air leaks after the MAF. If you don't have a good seal between the TB and manifold you will get a high idle.

It should not take any driving around for your idle to be below 1000 RPM.
