weird clutch problem

[2gGSX]

No CEL, happens basically all the time.
Basically when I depress the clutch it feels like there's a bunch of air or something in the clutch line. It makes a squeaking noise, and feels like there's a slight reverberation in the clutch pedal.

I know this is a vague question, but it's really been bothering me

could be the master cylinder......try bleeding the system.

On closer inspection...
I'm 99% sure it's not anything w/ the pedal/spring mechanism on the pedal side
When I push it in slowly, there's a very loud groaning from under the hood from about 25% depressed to 75% depressed (haven't pinpointed, but I'll just assume its from the clutch )
Then when I let it out slowly, there's a slight "pop" twice while letting it out, once again close to 75% depressed and again at maybe 30% depressed.

Any ideas?

mine did that..bleed the lines, fixed mine..though it still makes a little bit of noise..works great though.

okay wait.. so it pops when you are engaging the clutch? or when disengaging?

Makes a loud groaning noise when I engage the clutch slowly, and when I let it out slowly there's no groaning noise, but at two points there's a "pop" (that's the best I can describe it)

Ok more information

Thinking back, I have no idea what type of brake fluid the guy who owned the car before me put in, so it's possible that I mixed DOT3 and DOT4 fluids

An update, when I push down the clutch there's little if any noise now ( maybe this only happens after driving?), then when I let go, after about 50% or so there's a pretty loud pop, and a slight jolt in the clutch pedal with another much smaller pop/jolt right before I completely let off.

I'll check again in the morning I guess
