Well to know if catalytic is blocked some obvious symptoms like pickup reducing a lot, car doesn't respond properly with acceleration like we say acceleration becomes heavy, increase in fuel consumption etc and lastly just open the cat converters and have a look at them when I got the cat converters opened all the holes were really badly blocked it was completely chocked so changed it, specially the fuel consumption dropped to almost 8 km/l in my car. The sound also became a bit loud and heavy specially when pressing the accelerator
I also got all the things checked not only the cat converter changed
Cleaned the throttle body, injectors, injectors rail, map sensor, egr, spark plugs (dense ik20 irridium), air filter cleaned, checked the fuel pressure by fuel pressure gauge that was OK otherwise would have opened the fuel tank and cleaned the fuel filter but fuel pressure was OK so not required
Results, The car is very responsive and light in acceleration now it responds with the accelerator and no difference in pick at all with or without A/C it has become just like when it was new almost, the sound is also normal now no heavy or loud sound while pressing the accelerator
As far as mileage is concerned will check in by next week as gott the cat converters installed yesterday and filled the tank full today
