A choked catalytic converter cannot be cleaned even if you pray to it to send black hilux vigos full of SSGs to it
Choking happens when the honeycomb matrix melts down and blocks the pathways, such unit cannot be cleaned. The scam “sir ye peekup check karein” is a roadside robbery taking place, because the converter operates at 700c in its core and in waves, everything cleans out itself.
The peekup check karein zara gang basically just do nothing and clear the ecu adaptations that it has learnt over time. Result is “original wali parfarminss”
The real and actual test of a “blocked catalyst” is done with a pressure gauge placed before the converter (best place is precat oxygen sensor), we should see “zero psi” at all rpm ideally but maximum is allowed till 1 or 2 psi at full load (full air gulp).
The above written is the worldwide standard of testing and has repeatable mathematical results with actual answers, not “peekup check karein, kinna solid hai, heavy chalrahee hai” 🤣
