Weird Idling
I just drove my car to get some food and I realized that it was idling at around 750 however it was going up and down from 750. Also there is a vibration through the car while its idling. I'm just wondering what I should check. As well as two days ago it threw a P0440 code at me so I removed and put back the gas cap and removed the negative cable from the battery for about a minute and I haven't seen the code since. Any advice would be greatly appreciated.

i read that spark plugs are a culprit when a car runs rough. can anyone explain what "running rough" means? i presume my car runs and fires smoothly but maybe it doesn't. i changed my front plugs this year but not the rears.
