Vibration And Growling Noise Around 2000rpm

[blueviol]

Hi,

Recently, after changing the power steering pump about 2 months ago, I have been experiencing some annoying vibration coming from the floor whenever I rev the engine near 1800 ~ 2000 RPM. At lower or higher RPM, it sounds and feels okay. It is so weird that it is happening at this band range only.

It vibrates the whole floor and I can even feel it on my feet.

I am not sure if it has anything to do with the fact that I had the pump replaced.

Has anyone had any experience similar to this or does anyone know the possible cause for this? My SC400 has the check engine and TRAC lights for several years now.

Thanks,

You might have a motor or transmission mount going bad.
