When it idles the whole car shakes really hard, the steering wheel turns into a blur. I had it misfire on me before and it turned out that the #3 cylinder was leaking oil. When I replaced that spark plug it was completely black and that made it run better, but not completely. I checked it again just tonight and it wasn't completely fouled like it was before. I checked all the spark plugs and they were bluish grayish, which according to a color chart means that the engine is running too hot. One cause of this that I've found out was that the fuel mixture is too lean. I just replaced the O2 sensor a couple years ago with an aftermarket one that I had to splice in, but I'm only halfway suspecting that might be the problem because it did the same thing before I replaced the O2 sensor the first time, but not nearly as bad. What could be the cause of the severe vibration? Could the airbag be deployed from the steering wheel from it just shaking that hard?
