Whenever I'm at a full stop my car seems to rumble and shakes a little. It feels like its coming from under me. The rumbling pulses on and off like everysecond or less. Does anyone know whats goin on with my car? Never heard of such a problem since I first started checking the forum.

Could it be due to coils or plugs? I bought the car with about 60,000 and now its at 85,000 and never changed either and don't know if the previous owner had changed them.

Thanks for any help.

 

Im curious to know, ive never hcanged my coil or plugseither and im at 78k. Havent felt too much rumbling but im not an expert so i wouldnt know when the coils go bad.
