my box wont start right???? help
 

I have a 2001 2.7 boxster with 68k miles on it and whenever I go to start it it will turnover but wont start. How I start it is by turning the key on t but not turning it over and hold the throttle down for 10 seconds then left off slowley and do that 3 times then it starts perfectly. it does this on every start im not sure what it is??? can someone help. Thanks!
