vibration under load

[titiksu]

Sorry to hassle everyone again.

Got engine vibration under heavy acceleration. Seems to be at engine speed. Is this normal for a B234R or is it something I should investigate?

Difficult to know whats normal. Really need someone who knows this engine well to hear it.

I'd check the engine mount first. The front and rear bottom mounts are not easy to see without jacking the engine up slightly. The top mount and the trans mount are easy to see.

At what rpm does it start and does it disappear at all?

hello, i've got the same problem with my saab 9000 cse 2.0 ltr LPT of 1995.

Vibrations occurs in all gear. It start round 3000 rev up to 5000 revs in general. They are the worst in second and third gear but also noticable in fift gear. I changed the upper engine mounts but not yet the bottom mounts. This wasn't really convincing.

Does anyone have the same problem and how did you fix it ?

Thanks
