Have had an issue with my car for a couple weeks now. The car idles low - around 400RPM, and then stalls out. Stalls out when putting it in gear.
MAF Sensor looks clean, have replaced the AC Compressor (since the pulley was shot and was about to throw the belt.) Replaced the belt along with it. Have replaced the battery (One code that popped was "Keep alive voltage low") The IAC Valve looks clean, the vacuum lines aren't cracked or leaking as far as I can tell. I'm unsure where to go, as I've grown tired of putting parts in. (Along with replacing both front hubs / bearings, lower ball joints, and Axle shafts two weeks prior to this issue starting)

One common problem is PCV valve system failure and may not set lean code .. Check ALL related hoses/tubing and the valve itself .. IF hoses feel 'mushy' .. replace all hoses/tubing and the PCV valve using Ford parts... 'Some' aftermarket PCV valves have insufficient internal parts! .. Some of these components are difficult to see, look closely.
sorry for the late response. I have checked the PCV hoses, have found no issues with that. I pulled the PCV valve and found it a little gummed up, so I went and purchased a new one, along with a Throttle position sensor to be safe. I will reply again tomorrow when I install these parts and see where it leads me. After that, I'm not sure what else it could be. The alternator is putting out full voltage, the battery is brand new (less than a week old).
