For a week now, the car just refuses to start at some occasions. When i turn the key, the check engine light doesn't turn on at all, the car does not even try to start. Maybe it is a safety measure. If i try again after a few minutes, everything is ok, i turn the key, the check engine light turns on, then i start the car. The strangest thing is that there are no errors, when we connect with a computer. Also the check engine light starts blinking at some point while driving, then it stops. I read in the forum about possible misfires. But i couldnt find information about the first problem.Any ideas?
