How can I fix my Toyota?
It's very likely that this has been caused by the catalytic converter. That engine tends to burn oil and the residue can clog it up. You could replace it, but that would be very expensive. Before you do that, I recommend you get a catalytic converter cleaning product from your local motor factor to put in the fuel tank, following the instructions. This could be enough to clean it up and get the car through its NCT.
