Hi,

My first thought is a plugged catalytic converter. Are there any odd sounds or smells from the exhaust? If so, remove an oxygen sensor before the converter. That will allow additional airflow. It won't be perfect, but if the converter is plugged, you will notice a difference in power with it out.

Also, take a look through this link. Let me know if what you experience mirrors what you experience.

Here is a link that shows how to test one:

Let me know what you find or if you have other questions.

Take care,

Joe
