hi guys i read lots of posts on vibrations and most lead to missfires. but i just replaced all ignition components so i can rule that out. i was wondering if the timing chain could be worn causing a vibration, or a fuel delivery issue? car has 337000 km. this is definatly an engine vibration as it does it under various loads.
thanks in advance.

Re: slight vibration
Have you checked the engine mounts? Have a friend rev it while you check the movement of the mounts.

Re: slight vibration
100% yes. I just replaced the TAM and front trans mount on my 97. It was so bad the whole car would shake. After replacement its like a new car.

Re: slight vibration
The engine always vibrates. The mounts keep it from transferring to the body.

Re: slight vibration
well it does it in high rpms in first and second gear, or if it down shifts under heavy throttlefrom 3-2. it only does it under 60mph. How do i check the TAM? i checked the tans mount and it needs to be replaced or made semi solid as it has a tear in the front of the rubber, noticeable under load.
