My 2019 Mustang GT CS convertible has a starting problem. I have installed competition cams, mother thumpers camshafts, 2005 shelby GT 500 throttle body, 410 gears, after market spark plugs, coils, wires, Hurst shifter, this car runs Fantastic, what a joy to ride around in, but, every now and then, maybe in a dozen rides, after parking the car, it will roll over and over, for 20 or 30 seconds, before it starts to fire and idle, it almost seems like no fuel, or too much fuel, what do you all think?

 

This is a 2009 year, not a 19.

 

Welcome to the forum. Please take time to learn how it is set up.

Every generation has a section for it - like your 2009 is in the S197 section.

You posted in the section:
So unless your starting issue is somehow related to how you use fhe forums, you are in the wrong section
