Car tends to die sometimes when you take your foot off the g

the car has days where it dosn't start very easy and when it does start when you take your foot off the gas it dies. when you drive as long as you don't stop or when you do you keep the gas pedal pressed in some to keep the rpms up. any help with this would be great.

Thanks,

Could be the throttle body and idle control valve needs cleaning or minimun air adjustment

Coolant temperature and throttle position sensors ??????????
