    Default CNG Problem in Civic prosmatic

    Recently i have observed slight jerk in gear change from 1st to 2nd and also on downshift from higher to lower gears on CNG only after changing my CAR timing belt/timing bearing and tappet adjustment. Any ideas if its related to CNG tuning or advancer problem. i have Tomosetta advancer/emulator installed in my car and previously gear change was smooth on CNG.

    probably he retarded the timing from standard

    well i have exactly same problem but its been like that ever since i installed cng even though i didn't do anything with "timing belt/timing bearing and tappet adjustment".

    I'd surprise if someone never had such problem on CNG as everybody tells me its normal with prosmatic + CNG.

    One guy also told me to through away CNG ASAP or get ready to change the gear in near future as sensors insides the complex gearing mechanism of prosmatic becomes faulty after using CNG for a while, can anybody confirm it?

    Hah?! Keeping a Civic Reborn on gas?! What a disgrace to the car!!!! ... Well your choice, but I would recommend you either remove that CNG from Civic, or get an xli with gas!
    No offence.. just my opinion! Cheers!
