I have a 2000Gt that I bought about 3 months ago (used). The check engine light stays on. The only thing that I know that car has is a set of flowmasters. It still has the stock H pipe. Why is this light on??? I unplugged the battery and reset the computer, but no luck. It stayed off for a day or two, and then came right back on. I have been told that this puts the car in "limp mode" and I am actually losing performance. Is there any truth to that? Any Suggestions on how to fix it?????
Thanks!
Luke
