Well, I don't really have any question at all, just wanted everyone to know what I've done if they have had some issues like I had.
It all started about last October. My check engine light went on, and I was having extremely poor gas milage (~3-4 mpg), eradic idle and overall poor performance. First code that it shot out was O2 sensor was stuck on rich. So we replaced the o2 sensor, nothing. Replaced spark plugs/wries, nothing. Then a new code poppped on. It was a PCM code. thats not good. I replaced the battery cable in hope that the computer just wasn't getting enough power since they were really corroded. Well that worked for about a week, then went back to poor performance and the light was back on. So after some checking, we found that the computer was bad. Replaced that but the light came back on the next day (which really pissed me off, since I just put $250 down on a new non-returnable computer) But I was on the interstate and the light turned off, which never happened before. Idle is back to normal, and getting 12-15 mpg again. Sweet, I guess it just needed to have a learning process or something. Hopefully it will last. The lights popped on a few times since then, but only for a couple mins. Do any of you think that might mean something?
