strange residual plot

I attach the residual plot of one of my simulations. Anybody knows why temperature residuals fluctuate so much?
I have a channel with two inlets, an outlet and a wall. I have adapted the implementation for using simpleFoam with temperature ("How to add temperature to icoFoam).
This results are given with an unstructured tetrahedral mesh. If I use an hybrid mesh with prismatic boundary layer I don see this behaviour for residual plot of temperature.
So I guess the problem is the mesh, but I am not sure.
If needed I can attach the modified solver.
Thanks for all the suggestions.

it may related to mesh as you said, so you may want to try some limited scheme in your fvSchemes
