there a lot of things you could do yourself to eliminate other factors, during your spare time when its cool in the afternoon you could to this process;

check first if engine support is OK, next is the transmission support, try to visually check your Drivetrain components like cv joint, cv joint connection to your wheel, then inspect your wheel, especially the hub, check your suspension visually if there's any loose nut or worn rubber parts and followed by the tire itself.

it could also be a simple loose bolt or nut inside your hood that makes the vibration possible... check your hood latch( determine if it fits and lock snugly no lateral movements), check your metal tubing like aircon pipes/steering pipes/ brake linings ( it may be rubbing with another component that could produce vibration when accelerating.

lastly check the underside of your car, check for loose bolts and nuts again, especially with exhaust connections, exhaust bolts, muffler support( rubber holding your exhaust pipe), check brake line support and bolts,

after you have exhausted and check all of the above i will presume that the cause of the vibration will me in the transmission body itself or engine itself, which will need a mechanic to check to verify.

Sir Miko,
Thank You for that. but when it vibrate i can feel that parang ndi humahatak.. could it be dahil di pa ulit na ttune-up? or is it in suspension side?

[miko101130]

when idle could you rev up into redline??

upon revving it up does it return to normal without aircon operating to around 600-800rpm?

di ko pa nattry.. but is it ok reving up that much in idle or in neutral?
