Keep in mind the current path for the flame sensing- it has to go through the spark wire and electrode, then through the burner, attachment to the case, etc. before getting back to the circuit board via its ground connection.
My take- make sure all of the burner mounting points are tight- I even run ground wires from the electrode mount back to the gas valve, or closest good grounding point.
I have thought about that run a ground wire from the electrode mount to the gas valve. What gauge of wire do you recommend?
It doesn't have to be much- the current for the flame sensing is ~15 microamps. I use whatever I have around- usually #14, but that's overkill, really.
