vibration in gas pedal 06 accord v6
 

I notice a vibration about 40% of the time while driving. It is usually while I am holding the pedal with light pressure to maintain speed, either on a highway or upgrade. I bought this car with 28,000 miles 2 weeks ago, have been to honda twice and they say it runs perfect both times, so I go home thinking I just dont how this newer more powerful car (than my 00 v6 accord) drives. Today I took a 3 hour trip and there is definitely a problem. I notice it while holding a steady speed on the highways, usually between 50-65, and at home i notice it while mainting speeds of 40mph, or slight upgrades. The vibration is noticible enough that my left foot (steady on the little foot pad/rest) feels a tickle/itch from all the vibration going up my leg.

Can somebody please give me a hint as to what this could be so I can go to honda and tell them what to look for so they understand and can fix it. fortunately its certified pre-owned so it will be free, but the hassle of back and forth with them is crazy, i need this fixed.

Thanks.

Hrm... the vibration is only in the pedal, not the seat or steering wheel, correct?

The throttle on 03+ Accords is drive-by-wire to my knowledge (our 04 MDX with the 3.5 is) so it's difficult to link the vibration to the engine.

There is a TSB 07-059 OCT 07 Engine - Excessive Engine Vibration/DTC P0A14

What does that mean?

Just had a motor mount replaced, helped some but still some vibration.

TSB = Tech. Service Bulletin
The dealer should have these so they can read all about it.

DTC = diagnostic trouble code
That's the error code (P0A14) that can be read with an ECU error-code-reader.
