When I got my 16v back home less than a week after buying it I was geting similar starting probs. I dropped the oil, cleaned K&N, added some Redex to my petrol and changed the plugs. This seemed to reduce the problem but it was still there, so I put the car on a dyno at a mates garage and he tuned it up a little and now it starts almost perfectly from cold. There is just sometimes a bit of low rev sputtering, but that last no longer than a minute. This sort of problem can be one of so many things, the best advise I had recieved was to fix all the cheap things first, giving it as much TLC as it deserves and with a bit of luck......
