My car is idling horribly. I have changed all the spark plugs & it seems like the last piston isnt firing. But i cant figure out why or how to fix this problem. I have been told to change the air flow mass plug but it is expensive and i am not positive thats whats causing the problem. I also cannot find the plug to run a diagnostic on my car, i checked under the steering wheel but no luck. Please help.
