The number one suspect for stalling at idle is the IACV either being dirty or bad.
You said it started right after the heavy rain so that leads to electrical, however check the simple stuff first.

 

I love my wife, who thinks logically when i dont, she has come to the conclusion that its a short in the fuel system that is causing my parasitic battery loss, and fuel system malfunction. Maybe, ill try in the morning and let you all know what happens.

 

They are called WO-man for a reason.
Like whoa, man, slow down and think.

 

ive been reading in the workshop manual, here is what i find.

If, during engine idle, the load on the engine is
increased sufficiently to cause engine speed to fall,
the ECM will sense this via the crankshaft sensor and
instantly advance the ignition timing to increase idle
speed and then energise the stepper motor to open
the throttle disc thus maintaining the idle speed.
Finally the ignition timing is retarded to its nominal
value.
The ECM monitors battery voltage and, if voltage falls
sufficiently to cause fluctuations in injector pulse
widths, it increases the injector pulse widths to
compensate.
On return to idle, the ECM will implement a slightly
higher idle speed to prevent the engine stalling.

So does that mean if the battery amperage is low, like mine, that it could cause this semi serious issue. It could be a bad crankshaft sensor, stuck iacv, tps. My god a mechanical 300 tdi sounds amazing right now.

more in the morning.

 

Go with a Series Ex MOD version they even have a hand crank and will go ANYWHERE.

 

Yes a series one ore two would be amazing to have, what i really want is a defender 110.

So this morning i

cleaned the iacv, wasnt that dirty. While doing so i managed to snap one of the very small bolts.

checked all the grounds, did another parasitic battery loss test, 0.03.
and nothing i pulled changed that.

pulled out the ecm and opened it up, no water, corrosion, or issues.

I also check continuity between the alternator and batter, good to go.

So im wondering if the battery is bad. or if i should use my eod training and blow this thing to high heavens.

 

Sounds like when my torque converter went bad on me.

 

Well that cant be so bad to replace, ive done whole trans replacements.

Oh and the problem seems to have dissipated, went three days of issues and now nothing, and its still raining.

 

What about your MAF and vacuum lines??

 

maf is there and good i believe, its less than a year old, and all the vacuum line on top of the engine looked good and were also replaced roughly a year ago.
