I have a friend whos YSL MX5 car keeps eating catalysts.
Any suggestions on the problem will be gratefully received.
Mazda checked the car out and say it is running normally but it is clearly running rich. MPG is down, power is down and the cats keep failing!
Rather than replace parts at random it would be good to isolate the most common/likely parts first and try a fix in this order.
What ideas or suggestions do you have for diagnosing and fixing this?
