Well it happened to me today as I was pulling from the car wash. My car took about 5-7 turns to try and get started. When it doesn't start immediately I have to keep the key turned for more than 5 seconds and then it will idle extremely rough and seem to almost shut off again but when I give it gas it's fine. It doesn't do it very often maybe about 1 a month but when it does it it scares me that I might have a bad filter or something. I know could be plenty of things going on but it would help if I could have some advice. Thanks in advance.
