Vibration still !!!!!!!!

[vsv6dude]

Not sure if this helps I recall ready on the other commodore forum some years ago a nagging vibration was due to the rubber supports for radiator failing.

After they were replaced the noise went away so it was claimed.

Im not sure if this is what it is could be completely off, but my vs had a really bad vibration and then i got the injectors flushed out and it ran really smoothly. It was only like 90 bucks as well. So might be worth a look

I still think its the torque converter or flexplate, torque convertor could have dropped a vane and the extra revs lock it all up hiding the problem until the revs drop

If you ran it on premium fuel and the idle vibration was not as bad it would rule out a balance problem wouldn't it?
I'm thinking if it shook the same no matter what grade of fuel you ran - it would point to something out of balance.
But if the vibrations lessened with the better fuel - it would point to something wrong with the fuel system or a sensor.

gday all again i still have my vibration threw my car and its getting very frustratin now . so i replaced ATS , COIL PACKS, LEADS , PLUGS , O2 SENSORS, TRANS MOUNT , EXHAUST MOUNTS ROCKER COVER GASKET . I have cleaned throttle body IAC TPS Plenum chamber. DFI board to remove corrison . the problem is it vibrates at idle in DRIVE and REVERSE only . but it drives very well when not idling . i raised the idle to about 900 rpm in neutral when hot and it helps but when its cold it sits about 800 rpm and the vibrations is there till it reachs normal operating temp witch is about 10 to 15 mins of driving , . i did have extractors put on and a high flow cat when i first got it but the vibration didnt accure tilll a couple months after it getting installed . i spoke to one mechanic about the exhaust being to stiff because the driverside extractor sitts lower than the passengers side one about an inch lower and it seems stiffer than the passenger one . so toke it the an exhaust specialist he seems to think its fine ????? no sure about that one . so i dont no where to aim next . i have had my HARMONIC balancer checked and its fine 2 mechanic seem to think my ENGINE mounts are fine. so my problem is that when my car is cold it vibrates pretty bad when in D but once warm it seems to brighten up a bit and seems less serve but still there . also when i go on long trips and have the car running up the highway for a couple of hours an i come to set of lights there is no vibrations feels smooth as ????? . any help would be muchly aprreciated as i have been trying to figure out the go for about a year now

Blocked fuel injector? Injector jet with a spray pattern not spraying fuel evenly might cause a vibration.

If it runs sweet & the motor moves around more than usual it could be the front bush in the auto - I had the drive part of my torque convertor break off where it has the cutouts for the pump to lock in & had to have the convertor & front bush replaced - I was told at the time that this bush comes out - so it could be a problem as well as a problem in your convertor as it acts like a flywheel. Do you have any noises - around the motor area ?? Is the vibes right throughout the car & are they there when standing still ??
