2002 D'ango 2x4 4.7
Stalls when coming to a stop, but so intermittently it's difficult to reproduce on command.
Note when letting off the brake when the engine starts to gurgle returns it to normal.
I replaced the MAP sensor, but that didn't fix it. There is no check engine light.
I was thinking the Torque Converter but I explained the situation to a transmission specialist and they disagreed.
I can't for the life of me fathom what's wrong with this thing.

 

Does keeping your foot on the gas a bit keep it alive? If so clean the idle air control valve on the throttle body and clean the battery connections (disconnect them to do this) with a wire brush. The IAC or bad battery connections can cause goofy issues like that. If the battery is old or weak it could also be an issue too.

 

It's the IAC.. Cheap part easy fix

 

IAC and TCS were top contenders, but when I had them fail in my Dakota, they threw a code. No codes on this monkey; unless it really is just dirty. I'll go at it with some cleaner and q-tips first.

And IAC's are not cheap. Local auto parts stores charge around $80 for one.

 

I'll bet on it being the TPS. Mine was beginning to stall too. Cleaned IAC and it helped a bit but quickly returned. Replaced the TPS and it's like a new car since.

 

You won't always get a code for those. I got my IAC for $20 on Amazon.

 

Same thing here. Just replaced the IAC and it's back to just bogging down.
It seems to happen right after I stop. You're going, you slow down, you come to a stop, 2 seconds pass... Bog bog bog - normal. Doesn't do it all the time, either. I'm gonna try the TPS.

 

Nope. Funny thing; when you throw it into neutral before you stop - no problem. Put it into drive - bog bog bog, normal. Gotta be the transmission! >

 

Bump for great justice.

So far, I've replaced the MAP Sensor, IAC, TCV and scrubbed out the throttle body.

I read on the super-reliable internet that after doing transmission service (replacement of the filters) if they're not inserted absolutely perfectly right that there's a chance air could get into the system and cause the problem. I did service this transmission with both new filters and a new shift solenoid cluster, but the problem took weeks after that to manifest.

There's also the possibility of the Torque Converter in the first stages of failure.

I bought a replacement vehicle for this thing ('06 Ford Escape...sorry Dodge) and am going to just park it in the grass until after winter.

 

So you never replaced the TPS?
