faulty o2 sensor??

[dosntknow]

my car has been feeling like its missing so when i have been riding i have been logging and caught a good 4-5 seconds that it was doin it. showed to a buddy of mine that also tunes my car he thinks it might be a o2 sensor being faulty. just want to post the logg and see what everyone else thinks....

I don't see a log.

Edit: Finally got it open. It looks a bit weird to me. It should fluctuate much more smoothly. Here's a log of mine when it started going out. It eventually wouldn't show voltage at all.

did your car run funny at all while it was goin out? any feeling like missfire or knock?

here is a log a bit longer. this one spans from when i left home till i got to work about 25 min of driving.

sorry nevermind the file is to big and dont know how to shorten it without cutting most of it out
