Has anyone experienced a vibration between 2200-2600 RPM's? It happens when im idleing and rev up to that rpm. I can feel it in the steering wheel and the pedels. Thanks

EDIT: Also iv been haveing this whineing noise coming from the right side of the motor. It sounds like a pully is going bad or something. I notice it alot more at lower rpms. I have 55k on my si.

 

Funny as it is....... Balance Shafts not balanced. It is in ALL 06 up Civics

 

what exactly do you mean by that? balance shafts won't eliminate ALL vibration. no strange vibrations here; car is still as smooth as when i got it.

 

Thanks for ALL your guys input!

 

Honestly, I think the vibration you may be feeling is the throttle body finally responding to your foot's input. The DBW causes such a lag that the car does not immediately respond when you rev it. Maybe that range is where the electronics finally realize you are putting the hammer down. IDK just spit-balling.

Do you mean the right side of the engine from inside the car? Because all of the pullies are on the left side of the engine (when under the hood facing the windshield). It is your PCV valve and more than likely normal. Had the same "problem".

 

Yeah its on the left side when standing in front of the motor. Thanks bro.

 

That whinging noise i was hearing was my idler pully if anyone cares. I just had to do a brake job on the si at 52k not to bad on a set of brakes.
