    Default Vitz 99 Break issue on AC

    Salam ,

    I have vitz 99 with CNG installed . Recently i am getting 2 major issues in my car .

    1.RPM gets too low specially on AC and car engine gets off almost on every signal .frequency in petrol is low and on cng its always .
    2.Breaks almost doesnt work on AC with petrol and cng both . This happens specially when the car is running at a low speed .

    I have checked couple of mechanics but dont get any satisfactory answer . There is one famous Guddu mechanic in tariq road who is saying its due to engine weakining and if you change only the engine assembly this will be solved .
    He serviced throttle body and also changed choke sensor to adjust the RPM . Also tappets are checked and they are not tight .

    Another mechanic from toyota motors is on a suggestion that it is nothing with the engine , there is something electrical fault

    Please give your experience only those who have faced similar problem and also how this was solved .

    Also if anyone knows some expert mechanic to fix this . Kindly provide his address and contact no .

    Waiting for your answers anxiously .

    This

    Check the vacuum pipes for leaks

    But

    Shutting off on ac is probably an electrical problem.

    Brakes seem like vacuum issue

    On petrol issue is due to dirty Throttle Body and MAF sensor, get both of them cleaned and your RPM issue will be solved.

    On Cng, it happens due to less gas , you have to open little more gas if you want to drive on AC, it will consume extra gas and your gas milage will go down, but hard break and engine shut down can be very dangerous so you have to compromise this on gas consumption.

    Thanks for your reply . I have already serviced throttle body and have replaced choke sensor , dont know about MAF sensor . As far as breaks are concerned , even on petrol and on ac breaks gets hard and doesnt work . More interestingly breaks get more hard when i am driving slowly on ac . When the speed is fast , breaks do work and they get little hard but not as good as without ac .

    Any suggestions ? still its because of low RPM breaks does not work ?
