Just went to turn on my 4-runner in which it turns on then shut off immediately. This is the third or fourth time it has done this. I normally let my engine run a minute or two before I drive off, but my boyfriend turns on the engine and drives off the second it starts. I always yell at him for doing this and I personally believe that he harms the car that way. Yes, there is gas in the car and has had it's most recent oil change. Anyone know what the cause of the problem may be? Thanks.
