    Well CC is choked due to bad fuel quality and deposits which plug into the CC. Toyota or any other company recommends changing CC after 70k but not all can afford it. CC is a mesh of ceramic plus nobel metals in it, and most of us agree not breaking it or they agree after getting their cars in trouble due to broken CC.

    I think one should give a try to spend only 600 rupees if it works wel rather to spend 4500 for replacing the sensors afterwards.

    Which sensor you are talking about ?? Why does only removing cost you 4.5k :s

    As far as I know, cleaning the CAT is useless as per the internet research. Breaking or removing is a common practice all over the world. The question is, what are the ill effects of removal?

    My dear Internet has some details of cleaning the CC as well, but you may know that breaking CAT is not a recommended practice. It ruins out your AFR and Oxygen sensors as well. The answer to your question regarding ill effects is that the post CAT sensor is oxygen sensor or sometimes called Lambda sensor. It functions by measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can use look-up tables to determine the amount of fuel required to burn at the stoichiometric ratio (14.7:1 air:fuel by mass for gasoline) to ensure complete combustion.

    The place is near to where I live and there are many workshops there but idn't know which ones are good.

    BTW, can you tell me if there is a good diesel mechanic there?

    I live very close to that. Probably the worst workshops I've gone too. My santro broke down in K block. I pushed it till there, they asked for 2500 to repair something related to the fan. I then called for my Liana and towed it to bhatta chowk. Costed 200 Once was sold fake oil there. Once was sold a fake sensor and my car was stranded for 3 days because of that. So yeah, you can't trust those workshops.

    Well You are correct, most of the mechanics there are untrained and rip off the money. I use to go there when i owned a santro and i go to the only workshop at the corner (school side). I went there through reference of a friend. Only mechanic is good. I dont recommend for any other work. Mechanic( Mr.Wahid) is very honest and loyal so i trust him and he does what he is told to do, not like other mechanics who insist on their way of work, no matter wrong or right.

    One thing important is that the car's work must be done by the mechanic himself not by his Chotaa's.

    My car's oxygen sensor had become lazy due to the Clogged CC. I had it replaced once I had the CC removed. Now, I'm enjoying a 50% better pick and a much better fuel average!

    Default Cat

    The mechanic removed the honey comb and the glass wool from the primary sound suppressor [ S^ S^] , which is being termed as CAT or catalytic converter , since then the sound of the car has increased . Holly Bummer what Did I do ):
    1. was it a catalytic converter is the first question
    I think the answer is NO.
    the second thing about this S^S^ , it is located very close to the fan plastic shield , and the glass wool in the S^ S^ was to prevent heat being transmitted.
    This piece comes with a manifold and is expensive. so replacement is a difficult to swollow pill. So this little cylinderlike S^S^
    should be wrapped with glass wool and should be clamped. It will resolve one issue. For sound issue Add a local sound supressor Known as dholki before the middle dholki.
    As for atalitic converters Cars having a pair of O2 sensors do not have a CAT . unless in California because they have co2 & Co issues. by standard CA law.
    Correct me if I am wrong i will appreciate

    I think the primary sound / temperature suppressor is being termed as CAT If it is a CAT then there has to be a smog pump air flow entering the cat. But there is a flow pipe after this Sound suppressor. Cars with O2 coupled with CO sensors do not need a CAT by design
    unless in california. I may be wrong

    Here are my comments:
    1. CATCON can be cleaned by high pressure air. Don't have to break it.
    2. Hi-octane also has lead in Pakistan, perhaps more lead than regular (check PARCO website).
    3. Don't fill up from Attock and PSO, your CATCON will last longer. Shell is best.
    4. In Islamabad CATCON's are cleaned at Sarya chowk by Imran silencer wall. Does good job.

    In some cases cat cannot be cleaned if it is chocked way to much. No matter what you try it won't open.
    This happened with my Vitz 2006.
    The best thing is to replace exhaust manifold from spare part market.
    I got it for 6k from bilalganj, it was brand new in condition and it's jali was completely white carbon free.
    My car's performance was top notch again.
    I recommend everyone to change it rather then breaking or cleaning it.

    I have been toying with the idea of removing the Catcon for a couple years but the fear of O2 getting fouled and burned and the car running too lean is stopping me.
    Theoretically, if Cat is removed, the exhaust gases will become richer for the secondary O2 sensor and the ECU will make the car run leaner, which will result is detonation and premature engine wear.

    Please correct me if I'm wrong.

    Dear Waqas
    Could you please give me the number and address of your mechanic, i have suzuki wagonr, its cathlatic is chocked.

    Thanks
    waqasjamil;4591589]Today i Got My Vitz's Catalytic Converter Washed and and Cleaned with High pressure air and petrol.

    I must say that the people who do the stupidity of breaking the CAT converter on the recommendations of the local learned mechanics do bad with their rides because the pick and power or my car is much improved and noise and rattling is greatly reduced.

    First I went to TOYOTA CANTT Motors to get it cleaned but they refused straightaway and told that they will break it instead of cleaning as they d'nt do such practices. Anyways then i went to my trusted old mechanic in DHA who did all the job and he was also convinced of cleaning it rather to break it.

    My mechanic told me that a person use to buy the broken CAT Converters from us @ Rs1200/Kg. He was probably not aware of the precious platinum present in the CAT Converters which is Used in jewelry making and mixing.

    Here are the Pics:-

    BEFORE

    The dis assembly and removing the AFR sensor.
    Toyota Vitz chocked CAT removal and Noise *SOLUTION* after CAT removal -1499859

    Toyota Vitz chocked CAT removal and Noise *SOLUTION* after CAT removal -1499860

    The AFR sensor, you can see has the deposits of so called unleaded fuel in Pakistan.

    The Senor is Denso, so if anyone has to change it for any reason, he can see the part number.
