Hey guys, i have a 3.1L, V6, Oldsmobile Ciera that keeps stalling and dying at stop lights. when i hit around 25-30 the car will not accelerate any faster, feels like it’s dying. then when i stop, and press the gas to go it dies right then and there. So far i’ve replaced Sparkplugs, Fuel Pump, MAP sensor, Alternator, EGR Valve. i’m not sure what to even look for on this problem
