    todays earlier i went to a cng kit installer.
    and told him whole engine missing thing.
    after thinking for a while he opened the engine bonet cover and placed some scotch tape on air cleaner where the throttle body pipe connects.
    before that the tape thing was placed on pipe where the air enters the air cleaner.
    he put that tape off and placed at the other end of the air cleaner.

    when i asked him why he do that the told me that there is a sensor in air cleaner which judge the air flow due to tape on air cleaner pipe air was not flowing that much.
    because of that it was malfunctioning and engine starts missing.

    now my car is doning fine.

    no matter how many times i say this, people will NOT listen...

    putting sticky tape over the air intake DOES NOT improve performance, it DOES NOT increase mileage, it DOES NOT increase pick, it IS NOT the proper way to tune up a car!!!

    putting sticky tape over any place in the intake only serves to choke the air intake and reduce air supply

    less air requires less fuel to burn
    less fuel+air mix gives less power for any power cycle
    less power means you'll end up pushing the car more to attain desired speed
    and pushin it more means less drivability and less mileage!!!

    Besides, if ur cng mixer is installed between the throttle body and air filter housing then you should be fine anyway. Enough negative pressure is generated to get the cng sucked in.

    lesson for everyone!
    if your car has to be duct taped at the intake then your mechanic is probably trying to dupe you and MASK the problem rather than solve it. Period.

    bhai its a shocking news about problems in engine with petrol after CNG installation,.....
    LISTEN DEAR, you have installed CNG after 5000km and now its about 13000km this mean that you have driven your cars about 7000km on CNG and you didnt face any problem but now your engine is in problem with Petrol, simple yar dont waste time and only go to TOYOTA company and got proper tunning up your car engine and thats it, may be some sorts of carbon in tappet or little bit some thing others, but LISTEN CAREFULLY your ECU is perfectly working coz You can drive your car perfectly on CNG... dont worry you will be relaxed after TOYOTA company visit inshallah... good luck..

    bahi saab i think aap nain meri first post pori tawajo se nhn pari.
    mn nain bataya ha k gari cng pe perfect chal rahi ha is ka matlab ye nhn ha k gari ka ecu theak kaam kar raha ha.
    ecu gari ko cng ki bajaie petrol pe chalanay k liay ha.

    2nd baat ye k agar gari petrol pe missing or cng pe perfect ha to is ka matlab ye nhn ha k gari k valve ya tappet mn koi problem ha kune k wohi sab valve or tappet petrol pe use hotay hain aur wohi cng pe.

    3rd. ye k agar gari k battery k terminal uttar k dobara fix kar diay jaie to masla solve ho jata ha.

    now what.

    plz mention k kis toyota dealership pe jaon.

    Default Ultrasonic fuel injector cleaning

    When a car which is fine on CNG and hesitates or miss on petrol. Show lack of power or becomes jerky and uneconomical, it either has a leaning fuel pump which is not providing desired fuel pressure or has clogged fuel injectors. A slack fuel pump can not be repaired therefore replacement is the only solution but the performance of fuel injectors can be restored completely.

    Our mechanics and even the users know only one method for cleaning fuel injectors that is pouring fuel additive to the tank. Additives only make partial cleaning and have many hazards associated with them. When poured in the tank, they come in contact with many such parts of the fuel system and engine which they are not friendly with.

    In the advanced countries injector clogging problem is dealt with ultrasonic cleaning. Ultrasonic cleaning has capability to clean stubborn debris from microscopic grooves, cracks and holes. Since the fuel injectors have tiny nozzles which are designed to atomize the fuel, they are almost impossible to clear with any other mean. Only 8% to 10 % clogging in the nozzle can cause an injector to malfunction. Ultrasonic cleaning is internationally accepted most effective process for cleaning fuel injectors. It is cheap and comprehensive solution for the problem.

    it can be due to fueling or bad plugs,injectors wont get cloged so much after only 13k,
    get platinum/iridium plugs n retune ur car,it will be good as new

    Yar there is no need of Air intake blockage in new corolla.

    As other people indicated, you may have some ECU problem.. simply go to toyota inshahAllah they'll fix your car problem.

    hey one thing your running fine when only engine is start? kiyon kay meri car mein ak problem aa rai thi kay when i convert it to petrol while driving on RPM around 3 it starts missing for next 1 2 kms but parked car ko jub convert karo tu koi issue nhi ata..

    drive your car on petrol for few Kms and i hope your problem will be solved
