hey guy's well i own a 1997 vt commodore 3.8 litre it chuggs at certain revs and now has a noise coming from the internal, i replaced the plugs and i have put new ignition leads on and it is running like a shitter, only under load. once it starts to pick up it runs perfect but then once i flatten it it splutters and then stops doing it, any suggestions. there is no water in the oil or vice verser so it can't be getting into the plugs to do this. i'm stumped, any suggestions would be great

Does the sound change when its underload? Generally a diff noise will be most evedent around 80 - 100kph when off load.

nah mate it isn't coming from the rear it is an internal engine noise when at idle.

Well ,diff noise will go up or down with the speed.Easy to pick up.

Bearing noise too but,it'll be sort of stronger then the diff,something between grounding and winding ,and if u try to make a hard left or right hand turns it will scream.

If its a tyre noise (hope they'r not Maxxis) ,it will show up more when u slowing down from over 80-90klms.

Good Luck.

i'd be checking your rear wheel bearings mate, my right hand rear one was totaly gone. when i was drving the noise was disgusting, it sounds like something rubbing. sends vibration through the whole car. by the way sorry for stealing your thread
