97 4.0 GC TPS cleaning
I have an intermittent sputter that only occurs when I restart the motor while it's still warm never when its cold. Basically it starts fine, I put it in gear, go a short distance like maybe a few hundred yards holding a steady throttle and the thing just sort of starts to lose power and sputter a bit. If I let off the gas and tap the pedal it clears right up and it goes on it's merry way. No codes are present. Other than this issue she runs like a champ.
I've seen many folks talk about cleaning the TPS and thought maybe cleaning it might help. So I took it off but damn if I can see a way to clean it, it's just a plastic block that bolts onto the back of the TB with no parts to "clean". Am I missing something here?

You can't clean it, you can clean the connections. I doubt it's the TPS, it would act up all the time and at a specific position. I would look at the fuel pressure and ignition system.

Fuel pressure checks ok even during a malfunction, about 48psi. FSM calls for 49psi ±5psi

i faced similar situation on my KJ, throttle position sensor was the reason for problems. i replaced it, no sputtering no stalling so far after warm up ( it acted like there is a broken o2 sensor sometimes)
i realized that when sensor gets warm, problems arised, i replaced my crank sensor no help. there was no codes either. we checked the idle control valve with chrysler terminal it was ok.
i hope this helps.

i've cleaned my IAC once. when i would start it warmed, it would rev up to around 2,300 rpm and i would have to shift it into gear hard.
about time to do it again.
