Welcome to AF

Do you have any check engine light on, if so, what codes are stored.

Replacing the TCC solenoid is difficult due to it's location. It is under the side cover of the transaxle and requires dropping the engine/trans down to clear the subframe rail.

Outside of what you already replaced, the TPS (Throttle Position Sensor), IAC (Idle Air Control) valve and FPR (fuel pressure regulator) are all causes of your symptoms.

Since it acts up mostly when you try to accelerate, I would suspect the TPS and FPR first, as the IAC only affects idle/part throttle operation.

The TPS you can test by unplugging it, hooking a digital or analog multimeter set to ohms to it and move it through it's range of motion. The change in resistance should be smooth and linear with no gaps, or sudden big jumps.

Check the FPR for fuel in the vacuum line (this would indicate a ruptured diaphram that is leaking). Also check fuel pressure with a guage hooked up at the schrader valve (should be 41-44psi, key on/engine off) and should drop 3-7 psi engine running with the vacuum hooked up. Unhook the vacuum line to the FPR, and fuel pressure should increase back up to near original Key on/engine off readings. Good luck!
