Stuck Intake Valve Problem

I remember reading back during the prototype phase of the RX-8 that numerous testers were having a problem with the high RPM intake valves being stuck closed, causing a drop off of power in the 6k range.

Was this problem corrected in full, or has it been known to manifest itself in production vehicles?

(I did a seach and found nothing, so I apoligize if this has already been answered.)

If you're talking about the problem described in this article then no, I haven't experienced it or heard about it since the car went on sale in North America.

I took my car up in rpm slowly but steadily (this in 2nd gear) and you could tell when it hit 6250 RPM...a sudden kick in the pants...and the power ports opened.
