    Question 1 SZ-FE Charade 84 Jerking Issue

    AOA Brothers i have recently Installed 1SZ-FE in My Charade 84 Everything is Working fine but when i Drive my Car for approx 15 to 20 km or when the Engine Reaches Optimum Temp , Car starts Jerking on Intervals . Drops RPM .and on a Traffic Signal When Car is in Idle Position i shift to 1st Gear it does not Pick up after two or three Jerks and pressing the pedal continuously it goes Away and Again on next Signal same Issue. And When Engine is left idle position after some jerks engine is off. This Only Happens When Engine is heated or reaches optimum temperature on Cold it Runs Well. I have recently Changed Stock plugs to Toyota Genuine Plugs Denso Iridium K16R-U11.
    Whats the Possible Error ? is it

    1) Any Sensor issue
    2) Any Injector or Coil issue
    3) Any Fuel Pump Issue
    4) or ECU Error

    Experts i need your Help in this Regard your Suggestions will be Highly Appreciated.

    Knowledge is power guard it well !

    Stick to one thread. Dont start multiple it wont help.

    1. You have probably a bad o2
    2. You are also running Automatic ECU on Manual Ride.
    3. ECU will not see any signal from VSS hence car is running crap.

    Brother i Strated a New Thread Because only you and Owais were replying and that thread had delayed response i need to sort this issue out ASAP . As you say that Car has Automatic ECU but i read previous threads of 1 SZ-FE they Say that Auto ECU has only minor difference in programming which doesn't effect the working of Engine . btw i called my brother in Bilal Gunj he says that its short in Market as soon as he Gets it he will send it to me .

    I will update the status as soon as i get the o2 sensor checked brother.
