I need to change my fuel filter and i changed my plugs like 7,000 miles ago. They should still be fine. And i have had this miss and i cant figure out what the hell it is. After driving home from school i pull in the driveway and my idle drops to like 3-400 rpms and almost stalls. Im gonna change the plugs and fuel filter soon. and i guess ill try to check the cops after that.. Im just getting so tired of having to fix this car.. Any input on what it could be would be great..
