my tahoe with the 350 will sputter between 3000 and 4000 rpms. it feels likes its pulsating and losing power. the engines light is not on either. the truck was sitting for a year, started driving it again and this problem started. i tryed changing the plugs and wires, still same problem. and ideas?
injectors are probably clogged and or weak. 96-00 had issues with injectors causing misfires without throwing codes. they came out with an upgraded injector assembly but it's around 3-400 bucks.
