I can't be certain about the instability, but Plot3D[f1, {ω, -100, 100}, {g1, 0, 150}, PlotRange -> {0, 10}] seems to show that your expressions appear to blow up for certain values of g1 and ω. I'm guessing that is because of your large complicated denominators going to zero. Simplify[Solve[ Denominator[Simplify[f1]] == 0, {ω, g1}]] might give you some hints about why that is happening.

I notice I can change the position of the "kink" at the right end of your graphs by changing your {ω, -100, 100} to {ω, -80, 80} or to {ω, -140, 140}. There are some warnings about convergence, but the "kink" appears to track that ω bound exactly. Maybe this is enough of a hint to figure out why the "kink" is there.
