Dear all, My car had some problem with the tapets. Idiot driver of mine took to a local mechanic who suggetsed that the problem is probabluy because of catalyst converter getting choked(these non sense mechanics beleive they are smarter than jaopanese engineers. They beleive that it is a useless part). That idiot removes by cutting catalyst converter with welding machine and installed a muffler of FX to fill the gap. later I visited the silencer USTAD(Idiot) to show me my catalyst converter. I was surprised to see that he had removed catalyst converter of my car which was just like barnd new and had kept with himself as trash. Later I got tapets of my car adjusted and the car is running fine (with some change of sound) This fact keepas bugging me. What should I do. MAy any one suggest?
