I had that happen to me on two different occacions and I've managed to solve both of them. The first time it was because I performed the throttle body coolant bypass. this is where one re-routes the coolant line so it does not go into the throttle body. It did help with the temp of the air going into the engine but it caused some pretty erratic idling. It didn't happen all the time, but every once in a while. I changed it back to stock.

As for the second time, I disconnected the vaccum line that runs into the cold start valve. It's a line that runs from a little solenoid inbetween the intake manifold and valve cover and the vaccum line runs to the intake piping. I have this disconnected and it was not a problem, the problem was when I hooked it back into the charge piping and then it started bouncing again but a couple of revs cured it and then I just disconnected it again. No problems yet (knock on wood, hahaha)

Well, hope this might help.

if it smooths out after the higher rpms then i am pretty sure it is the spark plugs.....if you are a do it urselfer i would jus go shell out the 30 bucks for the spark plugs and do them urself to see if it makes a diff....u proly need to change them anyways and plus, unless u have a warranty plan u wont have to pay all the $$$ calgary honda will charge u with "what is wrong" with the car
