Alright so my cars idle is rough like when its sitting you can hear it kinda putting. I have only like one idea on what it might be. Few things to keep in mind tho. My check engine light is one its been on. Went and got that checked the guy said it could be bad gas like months ago. So im thinking it could be the filter or pump might be bad. Also i have a slight oil leak around the oil pan screw. Which i can fix easy. So does anybody have any ideas. Thanks!!
