I've got a pretty weird problem with the ignition: I stick the key into the ignition, twist it to the ON position and everything starts fine. BUT, if I jiggle the key gently and pull gingerly, I can actually pull the key completely out of the ignition, and the car keeps running as if nothing happened. I can also do thus when the ignition is twisted into the other positions in which the engine isn't turned on but the interior lights and other accessories are.
Then, I can stick the key back into the ignition--maybe just by a little bit so that 80% of the key's length is still outside the ignition, and twist the ignition down to the off position, and the car will stop.
Is this a big problem?
