And you have no check engine light? Maybe the bulb is burned out (mine was in my ef)? Sounds like you should be throwin a cel with this problem...maybe a map sensor issue because it is limiting the rpm's. I would start with checking the check engine light bulb, then check the map sensor (...check inside the Honda Map sensor plug (the bit on the manifold). The pins are labeled with V O G - for Voltage, signal and ground. With ignition on check you get 5V between the corresponding pins on the grey plug V & G. then you know power is good to the sensor... next check plug the grey connector back in to the map sensor and spread the insulation slightly on the wire so you can test voltage.... Check between O & G's (signal & ground) corresponding pins on the grey connector.... stock map will give 2.85v on a good connection)
