not good wendy, most likely cause is a blown cylinder head gasket, but have someone check to make sure the thermostat is opening( if you let the engine idle for around 10min the top radiator hose will get hot when the thermostat opens if the engine overheats before the top hose gets hot then replace the thermostat) if the thermostat is poening then supect the head gasket.
Leaks on the engine are commonly misdiagnosed. I have had a lot of people think that the "head gasket" is leaking when it is actually the "valve cover gasket". Find out the actual configuration of your engine before thinking the worse. A good look to confirm exactly where the oil is coming from could save you a lot of money.
1st check the condition of the oil by checking the dipstick. If the oil looks milky then it's a head gasket issue. If oil is ok, refill coolant, start vehicle and let it run for 5 to 10 min. If you notice alot of white steam coming from exhaust then it's a head gasket. After vehicle reaches normal operating temperture, shut vehicle off. Now you're gonna have to check each individual spark plug. If you find one that's wet from coolant then you're gonna have to replace head gasket.
Pull the oil dipstick and see if you have a lot of bubbles in the oil. If your head gasket is blown you will have coolant mixing with oil causing the bubbles. If you don't see the bubbles, you may still have a bad head gasket but should consider that it may a be a bad intake manifold gasket. Look on the ends of the engine block - where the transmission attaches on the driver's side and the drive belt is on the passenger side. Look for signs of coolant leaking onto the outside of the block castings at the base of the lower intake manifold chamber (it looks sort of like the flattened bottom of a V) . If it's there you may just have the manifold gasket leak. My '03 T&C with the 3.3l had this problem. It ran rough, and only with no pedal being applied. Driving was tough to get it to the shop since it died at each stop light and required the gas pedal to be feathered to keep it running.
If you have more than amateur skills you can replace it yourself.
