Low end hesitation update

As an update to the hesitation issues with my car, 5 of my injectors
have a poor spray pattern. These were brand new in spring of 2001
when I rusted my original ones. I'm going to have them
professionally cleaned with the bosch tool or whatever it is (my
uncle has the thing) next friday.
My car also seemed to be running perfectly when analyzed. It had .02
CO emmitions, 0 of the P emmitions (I honestly dont remember what
that one is called, I just know there is a P in it). Thats also
without a CAT. The timing was dead on.
One thing I'm still noticing is my frequency valve is usually pretty
quiet under normal idle. But every now and then, seemingly out of
nowhere, it buzzes as loud as it can and the idle goes bazerk. What
I'm assuming is happening is the car is running lean via the
frequency valve (but not too lean), then fully richens it up just at
random. There is no envoronmental change. I dont know why it would
suddenly enrich the mixture to that extent. I'm almost suspecting it
could be a bad LAMBDA computer causing that. Thoughts? (remember,
new plugs, wires, cap/rotor, fuel filter, O2 sensor).
When my fuel injectors get cleaned, I will once again (3rd time since
owning my car) completely pull the intake manifold with intention of
replacing every single o-ring on top of this engine. The o-ring for
the fuel distributor and the gasket for the air meter housing will be
replaced as well. Since I'll be pulling all of this off, is there
anything else people can suggest I check/change while I'm at it?
(Water pump was done in 2001). Thanks.
