2000 Ford Expedition

Hi all,

I've been experiencing some problems with my Ford Expedition 5.4 engine. It starts fine and idols for a while then the engine starts to shrug and sometimes stalls at stops. Its not missing. Anyone have any ideas what it could be ? Maybe the PCV valve ?

Is the service engine soon light lit? How many miles? If the SES light is lit, pull the codes (local Advance Auto store will do for free) and we can get a good idea of what the cause is. I just got a 2000 and had similar problems. I needed a new COP and a new O2 sensor.

Idle Air Control Valve, dirty or failing.

2nd for the IAC Valve. Cleaned mine and it solved the issues. Some aren't as lucky and will need to replace it.

I actually replaced the IAC valve last year. Do you think it could fail that soon ?

Go to an auto parts place and have them read the codes. AutoZone and O'Riley will do that and I know there are others.
When I read your post I thought "vacuum leak".

Vacuum leak could also be the problem, if the codes show a lean condition Bank1 and or Bank2 then its a good chance the PCV elbow has cracked or split.
