Alright here's the deal. A few months back I thought my car was in bad shape...turns out I just needed new plugs and wires. haha Ever since then it's been running like a champ. Well a couple of nights ago the CEL came on out of the blue. The car wasn't driving any differently and it didn't feel like anything was wrong. I took it to get the codes read and it was an emissions code. A guy checked all of my lines and they were fine, except for a hose that someone tried to rig to the CAI. It was splitting at the end that connects to the intake. He told me to fix that and see what happens. Well, I fixed it and the light is still on, but the car still drives fine. Any ideas on what the problem might be? Oh, also an unrelated issue. My doors keep locking automatically about a minute and a half after I get out of my car. Any ideas on that?
