Thanks for the response it's a 2000 Pontiac grand prix gt 3.8 218,000km recent Maintanance oil changes every 5000k synthetic oil since new, transmission flush and filter, new brakes, tires, air filter, fuel filter, fuel pump, tentioner pulley, this car has been very very well maintained! All this work has been done under the last 5000km please do not assume that I don't take care of my car! There is no check engine light on and my car has thrown codes! I just got the parts to fix the two codes today and was wondering if anyone had the same issues.
