    Exclamation Nissan Sunny Car Start Issue

    Hi Pakwheelers,

    Good Day All. I am facing an issue with my Nissan Sunny 1999.

    When i switch on my car after 2 to 3 hour or after 10 hours, the RPM goes directly to 2000 then it take 5 to 6 minutes to come normal under 1000.

    Please advise.

    Waiting for reply.

    Bad Auto-choke it might be.
    Do you find any jerks while driving? Or any sort of black smoke or hesitation?
    Plus how is the consumption?

    I think it's not too big a problem. In EFI cars, ECU is assumed to keep the RPM slightly higher at start up to get to optimum temperature quickly.

    Temp needle remains near C or gets to the middle?
