    Question Vitz 1.0 engine cold start problem.

    Hi Guys,

    I am facing one problem in my Vitz 1.0 model 2001.
    In the morning when I start it although it starts on the first attempt but I have to put the foot on accelarator till it gets warm enough around 1-3 minutes otherwise it drop rpms and dies also In that cold engine state if I put it in gear again it drop rpms and dies. After warming it around 1-3 minutes then no problem and everything works well. It is driven through out on Petrol no CNG.
    I already got throttle body and Air flow sensor cleaned up but It didnt fix the problem.

    Any ideas what else do I need to get check up / fix ?
