My Camaro is showing these codes as what might be needing repaired/replaced...P0441, P1406, and P1655. Can you give me a short version of what to look at first? I have replaced the EGR within the last month.

P0441 is incorrect operation of the evaporation emission system (a leak). P1406 is a Chevrolet specific code relating to your car's computer monitoring the performance and operation of the EGR system on your car. Each code has several pages of test and you need the instructions in frot of you to do any meaningful testing. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://www.eautorepair.net/Marketing/Default.asp?VID=125669 and get an online repair manual subscription.
