Has anyone noticed this?

When sitting at a light in my 01 NSX-T, the engine seems to rev a bit on it's own once in a while. It lastsa bout 1-2 seconds and goes back to normal. The tach does not register any change in rpm but you definitely feel the it rev. It may not be actually increasing revs but, rather, just getting a little rougher idle. Is this a normal v-tech trait that I never felt on the 91 I had or does it sound abnormal? TIA.

Maybe it's your a/c?

It happens when the A/C is off too but thanks for the guess. Anyone else? I thought there would be more responses. It feels like a momentary rough idle, then back to normal.

I've had something similar, but the problem turned out to be that my shoe was touching the gas pedal ever so slightly. Make sure your carpet secure, and the floor mat isn't slipping forward and resting against the pedal. That is about all I can guess it might be with my limited mechanical skills.

P.S. Make sure that no sand has gotten where it shouldn't, that throttle by wire is touchy.
