    Default Vibration 2000 chev silverado 4.3

    I have a 2000 chev silverado 4.3 . There is a noticeable vibration when truck is idling and in drive (as when stopped at a stop sign).Vibration may still be there when driving but is not noticeable. I just did a tune up ,plugs, wires, rotor and cap , PCV valve air filter and cleaned MAF sensor. Motor seems to run just fine. I have ordered motor mounts and transmission mount from RockAuto .But I really cannot see anything wrong with the original ones.Vibration can be felt on tailpipe and seems to go away when put in park.Any help would be greatly appreciated. Thanks

    Sounds like a vacuum leak. Check all hoses and connections. Good luck. Mine did that when
    the hose under the hood drivers side slid off.
