Sputter problem w/log

[danielsl1999gsx]

Hey guys, never dealt with a problem like this before so i need some help from you all. I am not sure how it happen but it started today as i was drive along to work. Out of no where I felt a hesitation in the low 2k-3k rpm range(2nd or 3rd gear). It comes and goes but sometimes during the hesitation my car will start sputtering hard as i would give it gas. It almost felt like a huge boost, so i pulled over to check but all my piping/ couplers/ hoses and they were all on tight. As i continued driving it happened again, this time with a cel on and a lumpy idle. I checked under the hood and notice my MAF plug was at an angle, fix it and idle return to normal(cel still on). On DSMlink the code 0100 came up for * Volume Air Flow Circuit Malfunction, i was thinking this was my MAF problem so i cleared it. Now i wanted to see if i could repeat the problem, this time with it in a log. As i started driving around i notice the blue line for my o2 sensor was reading low volts, around 0 at times and 0-.04 when the sputter would happen. The car doesn't jerk violently any more but there is still that hesitation/sputter at times. Could this be the cause of a sputter/hesitation? The log is kinda long, sorry but i was coming home from my gf house. If you see anything else out of the ordinary lmk, i dont use dsmlink too much, so this is all new too me.
Thanks

Wow coincidentally I'm receivin the same issues now except my car refuses to start sometimes. In the low rpms my car is spuddering and feels like it wants to die. I also have a real choppy idle now.

I get a start up problem as well some times, got to give it gas in order to start. Other times, it will fire up with no problem.

I have to press the gas pedal too! My car doesn't even start anymore :/. I checked my plug wires and they looked like absolute shit. Idk if thats whats causing my car to not start. I turn the key and the car wants to start but it doesn't.

hmm.. your sounds a bit worse than mine. I can get my car to start every time, it just needs some persuasion. I just want to know if the o2 senson should read 0 volts at all during its cycles?

Shouldn't the voltage of the o2 fluctuate? If it's pinned that would be a bad o2 or wiring? I think if it's pinned high it means the wiring for the 02 has a short, but you said it's low.

Check o2, plugs, and all the easy stuff. Do you know the a/f when it happens? I can't look at the log, on my phone.

I can be wrong, but I think it should go from .2-.9 volts right?

Yeah I was looking around and the o2 should fluctuate. But people were telling me it should never read zero, and mine would read zero for a while while driving or be stuck at .06 under load.
