Alright, I understand. There are a few things I would check first, It's very possible it is the PCM, as the PCM does contain the coil drivers and grounds the coils at the precise time to fire the plug.
First thing you want to check is exhaust
system back pressure, It's possible the cats are stopped up and you could have cylinders misfire because they can't breathe. This is a test that is done with a gauge that is screwed into the front O2 sensor port. If you have more than 2-3 psi of back pressure, then the exhaust sytem is clogged.
If you don't have a back pressure gauge you can use a vacuum gauge on the engine. should hold around 20 hg at 2500 rpm. if it's lower than that, could be exhaust clogged up.
Next thing to do, is use a scan tool to check your fuel rail pressure sensor , If it's showing low fuel pressure, (lower than 30 psi) I would replace the rail pressure sensor.
If all that looked to be alright, with your symptoms I believe you may have a failing PCM . But check those other items first. If it's just giving trouble when you throttle it up, It very well could be low fuel pressure or clogged exhaust.
