this just happened this morning and last night. when i start the car up cold, the rpm is high, then it slowly goes down as the engine is warmping up. once warmed up, i drive it a few streets down and i feel a bit of rattle on a red light, and it just goes away, the rpm is down to 500. is this normal? if not, fuel filter or oil filter? - Mike
