    Vibration at certain RPM

    Guest-only advertisement. Register or Log In now!
    Does anyone feel a slight vibration at idle when the engine is revving at around 700 RPM? It seems like it goes away whenever it idles at 900-1000 RPM.
    I have a CVT and I read from somewhere that the transmission just does that. Is this true? Or is it a motor mount problem?

    I have new motor mounts and it's still there. Must be a vacuum leak. Gonna built a tester this weekend and try it out.

    Vacuum leak would most likely make your car misfire.
    Could be the engine mounts, see if u can see any unusual fluid around them.
