Thank you for your suggestions on what it could be.

I had my entire exhaust system replaced about 2 or 3 years ago. Can the cat get plugged up in that short of time?

Not sure if you are familiar with the Canadian Clean Air program but every 2 years we have to get our cars tested?

Mine passed every test with flying colours and I would think that if my cat is clogged then it would not have done so well. Every reading that was taken was almost 0. The car is running very clean but sometimes it does feel rough?

I am going to replace the fuel filter and see if that will help? I have seen many threads say that the fuel pump tends to be an issue?
