I'm a little concerned with the VR6.

When i start the car on a cold morning or when it hasn't been started for hours, the car bogs down when i try taking off for a while. For example i will acelarete and the car wont move then as the rev's drop it will move forward and this will happen for about 5-10min then she's right. Then every know and then it will still bog down under load on take off.

WFT is wrong with her?
