Welcome to 2CarPros.
Has anyone check the catalytic converter to see if it is plugged? A plugged catalytic converter can cause this type of problem. And yes, low compression can do it as well. Take a look through these links. They explain the symptoms of a bad catalytic converter, how to test one, and in general how one is replaced.
Also. if you want to check engine compression yourself to confirm what they are saying, here is a link that shows how it's done. If you maintained the engine since it was new, I really find it hard to believe compression is an issue, unless you have a bad head gasket.
Pic 1 shows compression specifications. Keep in mind, most parts stores will lend or rent a compression gauge to you.
Another thing that can cause low power and low compression is a bad head gasket. Doing a compression test can help identify if that is a possible issue. However, here are directions for testing for a bad head gasket:
Let me know if any of this helps. As I mentioned, I really find it hard to believe low compression is an issue because of the mileage and you maintained it since new.
