Hello Everyone, So after almost 3 months later i have an update for my 2010 chevy impala 3.9L P0010 code that just would not go away kepping me from inspecting the vehicle. I ordered the engine harness which had to be special made because no one in the country had one, and was shipped from Detroit, Michigan. That took 2 1/2 months. So I installed harness and all my problems went away!!! So thank you for all your suggestions and comments and hopefully this thread will help others with this particular problem!
THE END V-)
