PCM Diagnostics & Tuning - Please Help with log.

I just bought a camaro and it has a hesitation thru the RPM range. I have HP Tuners and did a log at lunch. I noticed that my LTFTs are way off. I am fairly new to HP Tuners so I am not sure where to go next. I unplugged the MAF and the car runs great. There are no current DTCs but I did see O2 bank 1 and 2 sensor 2 in the history. Could this be a bad MAF or O2 sensors? I am not sure how to load the log file. Any help would be great. I don't want to just start replacing parts.

Are your O2's cycling? Is your maf reading correctly? It could be dirty

I cleaned the MAF first and it seems to be reading correctly. The O2s cycle but it looks like sometimes there is a pause.

When logging the O2's are the values relatively close?

Your hesitation may be caused by an old fuel filter. That is the most likely cause. If the car is not new to you and it has been running fine before, the less likely place to look is in the tune.

After looking at the log closer I realized that the MAF was only reading 1-2 thru the RPM range.. I replaced the the MAF and it is a whole different car now. Thanks everybody for pointing me in the right direction. Now I just need to decide what to modify first.

Awesome, glad you figured it out.
