Alright so ive had this car now since it came out and this has been happening right from about a year ago. Basically the car runs great all the time, but occasionally has problems starting. When I have the problems starting the engine I turn the key and it just wont start for maybe the first 3-4 tries of about 5 real seconds. When it does start the engine only idles around 150-200rpm causing the battery and the engine light to come on. If the engine does not stall during this time the computer will adjust the idle and the engine will catch after about 30 seconds of running terribly and blowing black smoke due to unburnt fuel.

Any Suggestions or Help would be greatly appreciated as me or the dealership have no idea why it is doing this.

What has already been done:
-ran with supreme fuel
-changed fuel rails/fuel lines/fuel pump
-changed spark plugs (only has 50,000 km on it now)
