Is there black smoke coming from the exhaust? Has the check engine light come on? Have you checked the catalytic converter for plugging?

Let me know.

I hate to say it but I think you have a bad head gasket. When coolant gets into the combustion chamber, it burns white. Have you been using any coolant? Also, check the motor oil to see if any coolant is mixing with it. Finally, I recommend doing a compression test on the engine to see if one of the cylenders has lower compression. If you need directions, let me know.
