I've been daily driving my 03 CL600 for months now with no issues. Recently it has hesitated on the 2nd start of the day. It fires right up with no hesitation when I start it for my morning commute, but when I start it for the second time (2-3 hours later) it tries to start for 2-3 seconds before firing up. It does this every time now like clock work. I could start the car 6 times in one day and only the second start will hesitate.
Anyone have an idea of what could be causing this??
