Whenever I start my car up, after it has been sitting for at least 4 hours, it kinda sputters the vibration from the engine pretty much shakes the inside of the car, not violently just a little bit of vibration, for a little while, even when I put it in gear, I give it some gas it still sputters, it goes away pretty quickly, but it just started doing this, it has kinda got me thinkin...whats going on here

Any lights on? Could be your baro sensor, maf sensor, iac.... There are just too many darn things out there now....

just the check engine light is on, I was gonna go to Autozone tomorrow, to get them to read it and see what it says
