I had exactly this same issue. Also, I was going through O2 sensors on the right bank because the TPS was sending too much fuel to that side.
Replaced the TPS, and the hesitant accelerations were gone, and the Check engine light stopped coming on (had to replace the O2 sensor too though)
You definitely have a TPS problem. It needs to be replaced.
