anyway, from the look of things, i really have no choice but to look for the parts that you said... so right now, what i feel that the VTEC is not engaging, its not really engaging, right? even if the engine has no problem revving up to cut off? so every time i ran the car up to 7000 rpms its just running on 12valves? the regular 16 valves is not running and also the wild cam? maybe that's the reason i am having bad gas mileage... your thoughts will be appreciated again...
