for this, i would clean MAF and throttle body well.
then take it to s shop and have them perform a injector service.
they disable the trucks fuel pump and feed it alternate source
thru fuel rain.
i do these often in my shop for GM LS engines with hard start, rough idle, stalling
at low speeds cornering.
other thing it check the trans fluid level, a low level will cause this too.
