Default 04 Ram 1500 SLT 5.7 just shuts off ??

Hi Guy's, I just joined this forum,, going to pull my hair out or push the truck off a cliff! Had it to the dealer 4 times ! This truck has run good for me for a year. Now it will just stalls sitting at a red light or slowing down. Seems to do this at low speed driving, alway's starts back up. Dealer has replaced many things, problem has not changed at all. I have read others have had to have a software upgrade and a EGR replaced ?

Please advise with anything that could point me in the right direction, so I can point the Dealer in a better direction to fix this truck.

THANKS !!!!!!!!!!!!!!

There was a TSB out for that a while ago. PCM flash was the fix. Even though I've never had the problem (I believe my 180* thermostat has a lot to do with that), I know it fixed it for the ones that had it done.
If you ask me, you got a pretty **** poor service dept at your dealer, 4 trips! This was a big issue on '04s and '05s a couple years ago and they'd have to see the TSB if they went to the computer to troubleshoot your problem...
BTW: If it's not a dirty TB or something causing it and IS the low idle, PCM flash issue, putting in a 180* thermostat for all of like $10 will fix it as well...

A thermostat swap would be great if that will help? This truck struggles a lttle when I first start it when cold and may just shut of as I slow down at a light, You think that is a thermostat issue? And I agree the Dealer I take it to might not be to good? It's the only one near me ...

Thanks for the info !!!! please explain the thermostat, why that coud solve it...

It's not an issue of your thermostat being bad, it's a band aid. The issue is the stock, unflashed tune on '04 & early release '05s have a tendency to have the idle fall too low and stall after the truck comes up to temp, when not receiving gas.
The lower temp thermostat will "fool" the PCM into thinking the truck is still "warming up" all the time, resulting in two things. A slightly richer mix, mostly desirable for those with mods that tend to lean out the A/F ratio, such as CAI, Headers and Tuners (why I have a 180* thermostat as I have all three). The other effect is the PCM will run a slightly higher idle rpm, only about 300-400 rpm higher, but sufficiently high enough to prevent stalls.
You follow?

I got it ! However The truck struggles when first started (when cold). Runs better when comes up to temp ? It will stall when it up to temp also sometimes...

What do you think !!

the rough idle when first starting sounds like an evap system leak or a dirty throttle body. But ANY mechanic should look for those two issues right away for someone complaining of hard starting and stalling. Especially when it's such a common issue with Dodge trucks. Contrary to what many believe, a CEL will not always kick for a minor evap system leak.
The thermostat will only work for those who experience the stalling issue when the truck is up to temp (the common Ram issue) as the thermostat doesn't even become a factor until the engine temp reaches the rated temp of the thermostat...

i got this issue too. i am just about positive it's an evap leak.

Truck only does it after i fill it up from under a 1/4. soon after i've filled up, i'll stop and the truck will either shut off right away or start rough idling. a little bit of throttle solves it if i catch it quick enough. won't do it more than twice after a fillup.

Fix for me is to not let the tank get under 1/4, or don't fill it up all the way in one stop if it does get under 1/4. I just don't care enough to track it down any further.

Yep, I'd even bet that hat on it. Look for cracks in the lines, especially around the hose ends at the canister...

if it's dying with a half fill and running rough, your problem is worse along than mine is. lte me know if the fix works, so i know what to do if it ever gets bad enough for me to deal with it.

Hey Guy's, now that think back a couple weeks, I had a strange smell a couple of time in the cab of the truck. Could a Evap Leak cause a strange smell?

Thanks !!!!!!!!!!!

Hi Guy's, it's been a while, just wanted to tell you the end result...

My truck is finaly fixed, the dealer ended up changing a fuel module ?

Not sure what's the exact name of it? I think along the way they fed me a bunch off Bull sh*t... Anyhow whatever they actually did, it seemes to be fine ! That fact that it was a warranty thing, I don't think they wanted me
to know to many details.... You know how the game goes !

Note: they so said no issue with the evap sytem >>>>

Thanks !!!!

Hello;
I have a 2005 Dodge Ram 1500 4X4 that at stops the Idle RPM drops down and dies. Does not matter as to what the fuel level is. Does not do it all of the time though. Trying to trouble shoot is a you know what. I cleaned the Throttle Body and do not know exactly if my engine has a Idle Air Control Valve. Anyone know at to exactly where it is located on the engine???

Hello:

I am having a similar problem, truck ran great, shut it down and the next morning it wouldn't start or run without having my foot on the gas, I disconnected and reconnected the battery and it ran good until i shut it off and then i started having the same problem. Any idea's? Problem just started so far all i have done is change the PCV valve. It's a 2003 ram 4x4 with the 4.7L

Thanks

For the OP, they most likely replaced the faulty rollover valve in the tank. It stops fuel if the vehicle rolls over (duh) but when it goes bad can cause the engine to stop for seemingly no reason. I had this happen to mine about a year ago and once the dealer replaced the tank, the problem has not returned.

Exactly what my truck does It's making me crazy I cleaned the throttle body replaced the egr valve.I was thinking the fuel pump assembly as I notice the gas gauge at e when it starts acting funny. It did throw a p0440 code could not find the cause reset the light and it has never come back on.
