HARD STARTING
Intermittently my car will not start on the first turn of the key. It will crank then idle rough around 500 RPM. Once I feather the gas it will come to life and drive normal. Anyone else experience this>?

Re: HARD STARTING (ICULUKN-C5)
That would be an indication of an injector leaking down when parked.The result is the fuel rail not being pressurized when starting,causing a hard start.The smoke is from the excess fuel being dump into the cylinder until it is burned off,also resulting in a rough idle.
This can be easily confirmend with a fuel pressure gauge.When you turn the key off,fuel pressure should maintain.If you have a leaky injector,fuel pressure will drop quickly.
You can also remove the fuel rail and turn the key to see which injector drips :yesnod:
