Hey mate..... If the car is runnning good.... Reset the code and do nothing !!!!
Just make sure you are up ta-date on a Tune-up (plug, wires), Petro and Air Filters.... If that is all good. Go to frigie and take out a long neck and have a "Rip snorter" of a day !!! Cheers.... JzJzz , and the Man from Down Under.... |

Re: 2003 Cavalier code P0420
Hi,
Thanks for your help. Being a Auto Body tech I am not up to date on modern cars. The car belongs to my sons freind. I will check the plugs and wires and filter. Now off to kill the rest of that 12 pack. Thanks |
