2000 S40 intermittent Hard Start

[stickbrick]

Hello
Ok I have 2000 s40 1.9t i am having an intermittent hard start issue I tried searching it but have only come across cars that will not crank mine cranks fine. this is a one one in 4 or 5 start problem temperature has no effect on it. here is what I did recently to get this car running I bought it not running
New plugs wires and coils
New cam sensor
cleaned out cam solenoid
New fuel pressure regulator
all this made the car run great and it still runs great just hard to start on ocassion about every 5 starts
And a soft code P0300 which goes away after driving

Problem solved
It turned out the new ignition wires from the local parts store had the wrong ends while they poped in just fine to the coil there was about a 1/4" gap between the contacts replaced wires car is great now
