How do I go about checking which code my car is having a problem with? My car is stalling when on a ramp, (front end down), and when I first start my car it's idling really high (and goes up and down) for a good minute or two and then it starts running OK. And while driving, the acceleration is jumpy, as if I'm tapping the pedal, until I get to a steady speed. Feels like it's dragging on acceleration. Service Engine Light comes on at random, and I can get it off by restarting my car. Any reasons why this is happening and/or how I can check it with these codes? I've never checked a car with those kind of codes and heard about them and am interested in seeing what my car tells me is wrong. :)
