99 chevy k1500 acceleration issue engine stumbles
my 99 k1500 will stumble when trying to accelerate around 50 mph, if i step on the gas it will stumble. my CEL was on for mass air flow sensor, the truck did this stumbling worse before i changed the MAF sensor. Thr truck runs better and idles nice it drives fine and accelerates fine under 40 mph or so but still stumbles..
