[malik497119718]

hi guys , my cultus is missing in low rpm (from 1 to 2 rpm) but there is no missing on long dirve or over 2 RPM & no power loss or miss fire .

car easily reach 120 in fourth gear & i drive it only on petrol ?

any suggestion ? vaccum pipe issue ? or timing issue or slow jet issue ?.

check fuel filter and fuel pump. engine not getting enough fuel at low rpm.

Probably bad air filter, maybe bad air fuel mixture. did you tempered with mixture?

[malik497119718]

I didn't check the filter but changed fuel pump month a go because old one was choking after heating but on high RPM it's fine.

[malik497119718]

Air filter is changed just month ago and I didn't changed mixture setting

[waqar19]

check fuel filter please.
