While driving at low speeds engine stalls rpm drops and acts though its going to cutout pushing accelerator does nothing after 10 secounds it seems fine and drives fine at higher speeds.

 Ive replaced throttle body and Cat converter,fuel filter,checked fuel injectors, idle vacuum was 21 inHg steady needle,removed VTEC selenoid valve, screen was clean and plunger smooth. It seemed fine for two days after removing selenoid valve but started acting up agian.

Anyone have any clue to what it could be?  

if the engine light is on then i would probably check the o2 censor cause my boy had the same kinda problem does it max out at 6000 rpms then it feels like its going to give out and  then it runs fine, i think it might be the o2 censor there pretty cheap and easy to install  

Ive already changed out the O2 sensors. It gets better gas but thats all.  

The engine light is off. and the Honda dealership said they dident find anything wrong?  

If you're still having problems, get Top Dead Center (TDC) Sensor checked.  For some reason it is difficult to detect.  If that is the problem, part and installation should cost no more than $250.
