If the vehicle isn't overheating then it's probably not a blown head gasket. There could be a problem with the oxygen censor.

To replace the exhaust manifold on a 1998 Plymouth Breeze 2.0, first disconnect the battery and remove any components obstructing access to the manifold, such as the air intake and heat shield. Unbolt the exhaust manifold from the engine block, taking care to remove any remaining gaskets or debris. Install the new manifold with a new gasket, tightening the bolts to the manufacturer's specifications. Finally, reassemble any components you removed and reconnect the battery.
Probably a blown head gasket. If the car has an (engine) oil cooler it might be a leak there too.
