Have you checked the codes?
The next day after this happened, the VSA was no longer on, but the malfunction warning indicator was still on.
I took it to both O'Reilly and Auto Zone for computer check - both read same code:
"P2138 APP Sensor A/B or 1/2 TPS D/E - Incorrect Volate Correlation - Code P2138 indicates that with the ignition on the PCM detected the difference between the throttle/pedal position sensor/switch D signation and the throttle/pedal position sensor/switch E signal was greater than the maximum allowable value"
However . . . I had read that a few people resolved the issue completely by tightening their gas cap.
So I stopped and put in a half tank of gas and made sure to tighten the cap with several extra clicks. I got in, started my car - and the malfunction light was off. It drove fine and a few hours later I went out and started it up - no warning lights on. As of today, the warning lights are still off.
In fact, the Acura manual I have says the gas cap may be the possible source of the problem.
What I now wonder if that IF that did solve the problem and caused the warning lights to be on - would the Auto Zone computer still show the code for the APP sensor since the malfunction indicator is what lights up for that issue?
I hope this was the fix, but I'm not feeling confident yet because frankly my car has had a "push/pull" feel when accelerating from a stop sign, etc. for a long time now, so that may have been the first symptoms of the APP sensor going out, and this gas cap may just be coincidence or something. ??
I'm now debating about whether to go ahead and order the APP sensor just to have it here in case it happens again.
