Well sorry for the poor use of english. It's just that the advice from the internet included changing the oil, changing the cat , changing the air filter and finally changing the car , just trying to make the point that this is perhaps the cheaper option.
They are only as good as the maintenance done on car regularly,if you dont bother to keep oil and filter changed,plugs and air filter changed you will have less chance of an emissions pass.Had to scrap a few because limits could not be reached.
