    CNG parr chalao as its designed for CNG only. Simple when you have made changes for CNG setting like blocking Air intake puncturing the engine for CNG then how it should perform 100% on Gasoline again, please tune it for Petrol plus CNG

    gari pehlay 5000 km petrol pe chali ha phir cng pe chalana shuru ki.

    lekin problem bohat unusual ha.

    agar gari mn lagi battery k dono terminal uttar diay jaien kuch dair k liay or phir wapas laga diay jaien to phir theak chalti ha.
    lekin kuch arsa chalnay k baad phir missing karti ha petrol pe.
    lekin cng pe bilkul theak ha.

    @Hameed

    Work of Emulator is to send signals to ECU of car that itrs running on Gasoline and if its so thn missing should be on both CNG and Petrol while faulty emulator mostly causes ENgine Check Light to go ON.

    Simple Tune Up can resolve the issue as CNG Setting is not working for Gasoline.

    hmmm.

    emulator bhe change kar k daikha tha.

    lekin koi farak nhn para.

    ye masla siraf tab ata ha agar petrol pe drive karo.

    cng pe koi masla nhn ha.

    dosri baat k agar battery k terminal thori dair ko utar k dobara laga diay jaien to phir ye problem nhn ati ptrol pe chalany mn.

    lekin phr kuch arsa cng pe chalao to yehi problem aa jati ha.

    FairLeo. The situation under which your car runs fine on petrol as you told is just after removing the battery terminals and putting them back to their own position. This is true because once you remove the terminals the memory of the Computer chip (CPU) residing in the engine is refreshed once you remove the battery terminals and put them back. This means that your car's CPU might have been corrupted, may be its operating system . Get it checked from Toyota Motor Company. I am sure the problem will be resolved by then.
    Please do so and also give me the feed back.

    Removing Battery Terminals too much can also lead to problem as if ECU(Car Computer Chip) goes dead i mean if it donot boot again then ur car will be dead until it visit some Toyota 3S.

    i doubt toyota dealer ship would take any responsibility

    as the mess could have been because of anything added afterwards. i even know a story in which a security system installlation(the lock unlock one) in corolla screwed its ECU
