:banghead: Need Help,,,

car starts and idles fine at first and then as it warms up it starts to run rough.

I seem to be able to hear some kind of vaccum noise but cannot pinnpoint it,
this car was given to me in this condition and not sure if i'm just hearing things.

I did do a vaccum test all appears to be fine.

I have done compression test and all is good,,the car does not overheat and it will continue to run but when getting it on the road, I cannot get any high end power.
