Do you have a code reader? A friend with one? Or can you stop by an auto parts store that will read the codes for you? When you have the codes, post here and we'll diagnose. Could be as simple as a worn out O2 sensor...

I had this error many years ago and it was a air injector pump of some kind. This happened many years ago on my 545

similar problem for me was a misfire in one of the cylinders. Had to replace spark plugs and ignition coils. $900 (dealer parts)

When i had that code it was failed secondary air pump to cats. There are two on my car one leaked and failed. If you can just get the code read the repair s can be DIY with the book.
