I just bought a 2005 GP GT and it seems to have a few issues. I have a lot of hopes for this car, but have to get past the small humps. I have a check engine light on. I ran the code and it shot up P0420. I am not yet sure if it is an O2 sensor or a converter. I also have an intermittent ABS and TC light. I am guessing that is probably a wheel speed sensor, because I am not getting any noise from the wheel bearing. I am glad to be here and will get pic up soon!
