    I agree with the burning temperature. Exhaust gas temperature is over 700 celcius degrees (1290 fahrenheit degrees).
    If the EGR cooler are blocked, I think EGR gas is too hot. I have cleaned the EGR cooler, and i saw like the weldingsparks there.
    I hope my misfire problem are solved the EGR cooler cleaning. egrcooler.jpg
