hey fyq hope u are doing good , i have a problem that i am sharing here ,
i feel car jerks on cng when engine is cold after few kms it runs smooth as sulk , i went to cng mechanic and he said the gas needs to open more but the last tunning i had done the mechanic told me its just perfect , car runs fine on petrol , it runs fine on cng aswell giving good milleage but the only problem is in morning when engine is cold the run gives few jerks and and than it becomes normal , car is carby cultus , air filter is reasonably new , plugs are in good state and all the things are intact , strange thing is car wont jerk all the time , some time even car is cold it runs fine , i feel when cng level is low car do that , i am not sure if its the auto choke that playing up as xulfiqar reckon its my auto choke , please tell me what u think wrong there , thanks .
