Hello,

My villager drives without hesistation during normal operation. However if we come to as stop, engine hesitates when transmission is still on drive and my foot is on the brake pedal.

What could the problem be, O2 Sensor? PVC or fuel pump, fuel filter maybe?

Thank you for your help..Have agood day.

Do you mean surging? idle going up down? You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! Also is your check engine light on?
Last tune up was?
