    Default Liana Idle RPM

    Aoa pws,
    My liana's idle rpm suddenly drops as i turn on the ac on idle. It drops from 900 to 600 on turning ac on and if headlights are on at the same time it goes below 5k with a sudden check engine light & then boosts again but drops again and again.
    Ignition coils tested ok
    Tappets adjusted
    Throttle body cleaned


    Any suggestion from all experianced fellows.....

    Without ac the car works fine 95%. Some times it drops rpm on 1st or 2nd gear...

    It could be because of a weak ground connection,faulty cng conversion switch,faulty charging system,weak battery,faulty IAC valve,check it accordingly.

    1- What are you doing with AC on in February.
    2- Is this AC problem on both fuels, cng and petrol.
    3- Idle RPM is usually ~950-1000 if its been recently tuned. After a few months, it can drop to ~800-850.
    4- Get it tuned at Suzuki and tell them your problem. Make sure your filters, and fuel etc are top notch.

    Don't call that dumb. That is physics. Read about windscreen fogging to find out why.
