This engine wants to idle down to a stall and sometimes pulsates to a stall.If i go to a stop sign it will die but not every time. It always starts right back up.I put plugs and a fuel filter in it . Pc valve looks good but im going to replace it once it comes in.Any ideas ?It is the 3800 engine.

Check the idle air control valve, EGR valve and the throttle position sensor
