Fluctuating residuals in transient simulation (transientSimpleFoam)

I modified the transientSimpleFoam to add a temperature equation and tried to run a case of t-junction from pimpleFoam tutorial with the exact same boundary conditions. The residuals I get, fluctuate a lot as shown in the figure:
The fvScheme is as follows:
fvSoultion is as follows:
The boundary conditions are exactly same as that in pimpleFoam case with T at inlet =400K and everywhere else is 300K.
Why is there so much fluctuation in the residuals??
