It sure sounds like a problem with fuel flow.

Wouldn't a fuel restriction make the EGT go up?

If you lean your engine until it starts to run rough, what happens (both to
TIT as well as to the individual EGT's), is that the EGT initially rises,
then it reaches a peak and begins to fall.

So what happens to the EGT will depend on where you are on that curve, when
the engine begins to run rough.

I have had problems, over the years, with clogged injector; clogged fuel
line; and clogged fuel servo. In all of those instances, the EGT for the
affected cylinder(s) went down when engine roughness was noted. Except for
the fuel servo when the problem became evident on takeoff and I was
concentrating on landing, rather than looking at EGT's.
