It may be as simple as your oil condition or oil level. If you have poor oil in your engine the VTEC system will not operate properly and when RPMs reach 2800 or so it will buck. If everything checks okay with the oil have the code checked for your check engine light/VSA light.

I had this problem on a Ridgeline and did just about everything trying to avoid taking it to the dealership. VSA stands for Vehicle Stablility Assist and if your light is flashing then you'll probably need to take it to the dealer and have the system checked for problems and reset. I don't know of any mechanics with the software that Honda has for this system.

I dont see any bulletins on the sensor having issues. the yaw sensor also referred to as roll rate sensor is located under the drivers seat. an option for you might be to replace sensor yourself and just have dealer perform the setup procedure.to replace you will need to remove the drivers seat to gain access and be very careful not to drop new sensor. might get lucky and install and light goes off with no further action,but if not most dealers will charge an hour labor to program/setup

I found this online. replacing the EGR valve would be a good thing to check as a VSA repair would be really expensive, it doesn't make sense that these should go bad, and it does not seem like it is something you can do yourself.

'This is going to sound funny, but your problem is not with the VSA. Here's what the dealer is missing in their diagnosis.
the way the Vehicle Stability Assist system works is that when a loss of traction is sensed (when one wheel is spinning faster than the other) then the control for the VSA starts to cut out engine cylinders to reduce the power to the wheel until traction is restored. When the control unit enables the VSA the exclamation point icon comes on and it will stay on until the engine is turned off.
Now for the twist--when the engine has a misfire that causes the engine to lose power then the VSA system "thinks" power is being reduced to restore traction and it puts the exclamation point icon on. So in essence, the VSA is being fooled into thinking that the system is enabled when in reality the problem is one of a reduction of engine power.
I have seen this numerous times on the Accords and Pilots. Almost always the problem is with the EGR valve. That doesn't mean that it is in your case, but my experience is that it usually is. Couple that with the history of EGR valve problems on the Honda V-6 and the the odds are strong that's what your problem is. However, anything that could cause a loss of power or misfire in an engine, such as an ignition coil breaking down or bad fuel could cause this problem.
In most States the things that can cause this problem are covered under a 3 year 50000 mile emissions warranty. I'd ask the dealer to do the diagnosis for an engine misfire and see where that goes.'
