If catalytic converter is choked heavy on petrol plus aluggish pick up, at 3 to 4k rpm u will hardly reach a speed of 100, with ac car will be like a 1000 cc car.
If there is a phati hoi sound coming than this means converter removed.
Guys also note that choked converters can be serviced plus converter should be serviced after every 10k it can be serviced by anybodu himself.
Reason for a choked converter is low quality fuel our hi octane octane level is also noy recommend for 1.8.
U can change octane level of petrol by using liqui moly octane booster or a mix of hi octane plus super
