Hi . I have nsx . While your inside the car engine
makes the car shake , a small shake , When you open up the bonnet you
can hear the engine working , the way it works is : its like you are
pressing the accelarator slowly than letting it go , every mechanic
said its a clean engine and engine is perfect and they have suggested
me to check the spurg plugs which i have , they work perfect , air
filter - it works ok , and i also added some engine injector cleaner
nothing changed , what else can it be? apart from that problem , car
runs great , drives really smooth . But apart from spug plugs , air
filter , injectors , what else may cause too engine shake ? any idea ?



thanks

 

have those motor mounts checked. if there weak or broken you will get shaking transferred to the frame


also if the Vtec system is not working correctly or if its been modified you may be in the upper end cam's and those at idle will shake like crazy or at least lope.
