Stalling issue at stop, replaced injectors, ECTS air idle control, TPS, coil packs. Cleaned throttle body and replaced intake manifold gasket. Still stalls at stop and stutters when you take foot off gas at highway speed. Codes are clear.

I am wondering if the MAF needs replacement becasue of the sensor being a little off but not enough to create a code which is common.
