Durango won't idle? *update* fixed.

Now it's a sweltering 0 out.  It's supposed to get up to 10.
It will start and I can keep my foot on it to keep it going but as soon as you let off it's done.  Any thoughts?  Am I looking at a fuel pump?  TPS?  Map sensor? I don't think it's my temp sensor; guage seems right.  Thanks-Josh

Wife's rig; I've got to get into it ASAP.  Thanks again.

    First thing I would do is replace the IAC (Idle Air Control). It is mounted to the rear of the TB and is what regulates incoming air at idle. I think you can get them for around $30-$40.

    If it is starting to get gummed up, cold weather could make it worse.

    You're absolutely correct, Kendall. My mistake  ;D

    The one shown was based on my 2000 truck. Your's might be different, but I doubt it.

    Thanks Kendall.  I used an ice scraper and the seat to get it up to temp.  It will idle now but sound like it has a miss to it (unrelated I think).  Can the IAC be cleaned without damaging anything?

    Dirty fuel injectors will do the same thing your having trouble with.  I've had and seen a few cars over the years that fuel injectors would get dirty and not idle but they would rev up.  The cold tempratures your having is probably aggravating the problem too.  running injector cleaner in the engine fixed the problem.

    Generally when a IAC motor goes bad they idle high not low.

     Customer Concern:  Once the engine is warmed up, it will not idle.

    Vehicle:  1994 - 2001 Dodge Ram 1500 Pickup 3.9L
       1994 - 2001 Dodge Ram 1500 Pickup 5.2L
       1994 - 2003 Dodge Ram 1500 Pickup 5.9L
     
     
     
    Symptom:  Oil consumption, spark knock, high idle speed. 
     
     
     
    System:  Emissions/PCM/Fuel, Engine Mechanical 
     
     
     
    Codes:  Possible P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 on OBD II vehicles 
     
     
     
    Problem:  The gasket for the bottom plate of the intake plenum is leaking allowing the engine to suck air and oil from the crankcase. 
     
     
     
    Test & Fix:  Testing for crankcase vacuum leaks is a little more of a challenge than external vacuum leaks. There are two ways that work pretty good. The first way is to remove the dipstick and place the hose of a vacuum/pressure gauge over the dipstick tube. Remove the crankcase breather hose and the PCV valve from the valve covers. Block off the crankcase breather hole in the valve cover. Start the engine and raise the engine speed to about 1000 RPM. Monitor the vacuum/pressure gauge as the hole in the valve cover for the PCV valve is slowly blocked off. It should show pressure because of blow-by gases past the piston rings. Do not allow pressure to build up in the crankcase. If it is showing vacuum, there is a leaking gasket on the steel plate on the bottom side of the intake manifold. The second and much easier way is to remove the air cleaner assembly and open the throttle wide open (with engine off) and peer down the throttle body bore using a flashlight. Check for oil pooling in the intake plenum. If oil is found, it also indicates a leaking gasket on the bottom side of the intake manifold. Remove the intake manifold. Remove the steel plate on the bottom of the intake manifold and replace the gasket. Reassemble. It is also recommended to de-carbon the combustion chambers using a suitable cleaner product since the oil consumption has probably built up some carbon deposits in the affected cylinders. A related document, TSB 09-05-00, is available.

    Generally when a IAC motor goes bad they idle high not low.

    When mine went bad, it would flucuate.

    Josh, you can try cleaning it with TB cleaner, I would clean the whole TB though, especially where the IAC enters it.

    Get the computer scanned for codes and run a can of SeaFoam thru the gas tank.

    Wouldn't a fuel fault trip a light on my dash?  Will a standard code reader do it or do I need some fancy model?

    Will sea foam work better than your average fuel injector cleaner?

    Thanks Steve-o.-JJ

    Just thought I'd update.  Looks like the "low voltage issue".

    Cleaned IAC and it still did it.

    Swapped in a new battery today.  I will post up results (hopefully good news).

    New battery seems to have resolved the issue; it's been a month now with no problems.  Whether it was letting the brain lose power or giving it a fresh battery that fixed it remains to be seen.  I'm just happy the problem went away.
