2000 monte no acceleration
 

hello my names ricky I have a 2000 monte carlo 3.4 that im having some problems with. first of all it takes a while to start, and when it does start I get no acceleration if I press the gas pedal but if I let it run at idle for about 15 mins and then press the accelerator pedal it accelerates. can anyone help me with this problem. :confused:
