hello friends..

my engine vibrates more than the rest of the rpm range between 4500-5000 rpms at both idle and moving.

what can be the reason ?

 

Define vibrates. Your question is vague.

 

ok. since one of my engine mounts are solid (the rear one) I can feel all the vibrations in the car easily. simply, eveything in the car vibrates. e.g. steering wheel, cluster, windows.

 

Would have been nice to mention that up front. You answered your own question.

 

well, so why are the vibrations around 4500-5000 rpm are MUCH more than other rpms ? I did not answer that I guess

 

TBH. I don't know what your definition of vibration is nor how much more YOU are perceiving it to be. Did this happen before or after the mount was installed? And why do you only have ONE solid mount? Sounds half-assed to me.
