Yesterday was driving home from work and came to a round about, slowed down and vehicle died (alternator gauge went below 14, oil pressure dropped below 40, and battery light came on). I lost all steering and brake pedal was stiff. Now vehicle continuously idles rough and will stall out if not on the throttle, idles 500 and lower. I have replaced mass air flow sensor, air filter, plugs, wires, O2 sensors, fuel filter, evap canister, alternator, and had throttle body cleaned. See there are many complaints filed of the same issues and wondering if anyone at gm has found a solution. Also have noticed gm has recalled the intake gasket but I have not received anything on this recall.
