starting issue?

[pdabbs911]

I have a 2002 X5 with a 3.0l. It has 135k miles. Thanks for the input 1st! Here is my problem: on some occasions I have to depress the gas pedal to start the X otherwise she does not start. There seems to be a slight bit of a rough idle at first if I don't give it enough gas with the pedal, but once I do give it enough, it roars to life and then after that she runs like the champs she is. There is not a problem with the idle after that. This symptom is only at start up and only on some occasions. It seemed to be a little worse this weekend and the only difference was a change in the weather. It was in the low 60's this weekend and nice outside. Has been a little colder around here this winter. Not sure if that info helps. I am willing to replace any problem parts with new as long as I can get my hands on some good DIY pics. She has a good bit of miles on her and probably needs some new parts any how. I don't mind as long as it is good maintence. I have done some searching, but not real sure what to search for. So, any suggestions would really help.

Thanks again,
