when i started the car yesterday i noticed a slight thudding sound... it sounded like a heavy piece of cloth that somehow got stuck on the prop shaft and started hitting the undercarriage... the rhythm was quite regular, though not always present... and it went away after a while. Car runs fine, no unusual sounds when running...just when idling.

when i put my hands anywhere on the front of the car a can also feel the thud, its a sharp thud enough to be felt, but it doesn't shake the car.

what could this be? knocking? missing?

i posted a thread about me removing my vac pump because it made a loud clattering sound which disappeared when i applied pressure on the vac pump cover... fearing it could be the culprit i removed it... it was intact, nothing was amiss. will be changing it out anyway since its the original vac pump.
