Unhappy E 46 no power

E 46 320 does not have power after starting it when the engine is still cold,the revs do not go beyond 2000 revs/min with the gas pedal all the way down,but it gains power after the engine has warmed up and its very sluguish interms of acceleration,on the scanner the only fault i get is the 0xygen sensor bank1(before the cat converter) which has been replaced and same problem,i have also changed the fuel pump,fuel filter,Crankshaft sensor & inlet cam shaft sensor,MAF and still no power,i have swapped all my igniiton coils with my friends with the same car,still same problem as mine are working superbly in his.
At times when you start it,it will just crank,then after 3 attempts or so it will start,its as if its starving on fuel,when u rev it,it makes this unusual noise as if i have installed a perfomance filter.
