Decided to give the engine-bay a detail today - pressure hose with degreaser... then restored the colour in all the plastics. Pulling the car up in the drive-way i noticed a high rattle when accellerating. Thought this might be because the engine was a little wet, etc.

Took the car out tonight down the freeway to the city and everytime i'd accellerate from a stationary position she'd shake and the 100km drive wasn't smooth either.

Possible diagnosis please...
