Not putting down power after VTEC engagement and ECO mode not working - 2009 Accord

Ok so I have a 2009 Accord V6 great car and all but these problems that I'm experiencing is abnormal for a car of this age and for Honda. The eco mode problem started a few months ago and it would come on and off multiple times, took it to Honda and they said its just throwing a code so they cleared the code but as I expected, this problem reappeared again and I found myself at Honda once again, got it scanned and now this time their saying its the cats which is very abnormal as this car is 4 years old and I just don't believe that could be the problem.

As for my second problem which is complete [non-permissible content removed], one night I was driving home and I stopped at a stop light when then the light turned green, a major problem occurred upon coming off the line, the car was not giving any power at all, it started to jerk like a manual car off a bad launch and was shifting horribly late, would not come of third gear and it was struggling to climb the RPM band. I barely made it to 40 km there was just no acceleration at all so I assumed it needed a tranny flush. So the next day I went over to my uncles shop did a tranny flush but it only helped a little bit, now the car pulls fine up until vtec engagement. When VTEC engages it starts to struggle picking up speed and it starts to barely pull at 5000 RPM. I would like to say its the tranny but that's complete [non-permissible content removed] for the car being so new.

Has anyone experienced this problem or have any answers or reasons as to why this is happening???

Thank you for answers in advance

    It sounds like your Cat could have failed. I had the same issue in my Altima SE-R 6-speed. My could would not accelerate above 40 with it floored. The more I opened her up, the worse it got because of the back pressure.

    My cat failed, but just a couple of months ago...My car is an 06. Once the cat was replaced I had all my power back...But, why did my cat fail? My car is consuming a lot of oil, but no blue smoke...maybe the cat was working overtime because of bad rings? I don't know...Engine has 106K on it...seems premature to me as well.

    You could temporarily disconnect your cat and see if you get your power back.

    good luck.
