I have an 04, 5.4 and it shuts off when I slow to a stop. I have had it serviced at a delear and it continues to have the same problem. Dose anyone have a solution? It almost caused an accident over the weekend.

Thanks
Paul

 

I have nothing technical as to how to fix it, but if it were my truck I would have it back at the dealer and enjoy racking the miles on there rental while they worked on the truck to make sure it runs right.

Good luck

 

Would have to agree with JDaddy here. It sounds like you are putting yourself and likely others at risk by driving the truck around when it could konk out at any moment.

This is clearly a warranty issue that needs to be resolved by a reputable dealer and not glazed over. If you have trouble at one dealer, find another and keep at it until its fixed. Thats my opinion anyway. Good luck and post with results if you can.

I remembered that some people had a problem like this and there is a TSB I believe out about it. The problem lies in the throttlebody/motor assembly for the drive-by-wire system. When cold or hot, if it has a problem it will intermittently fail. Your dealer should replace it without any hesitation.

Please go to the NHTSA website and fill out a report. My truck did this and it appears quite a few others have too. This could result in a serious injury or death. Ford needs to get this issue resovled immediately.

 

Paul (tpr)...How did the dealer "service" it, and how often does this occur?? I agree with the posts, it is a serious concern, needs to be documented at NHTSA, and needs to be corrected immediately.

There is a TSB out there, but I thought it only affected earlier production (when was yours built??). Earlier trucks may have had bad throttle bodies, and on later trucks a reflash of the PCM was the cure.

In the meantime, (I know this'll sound crazy), turning on the A/C will tell the computer to raise the RPM's at idle, and may allow the thing to keep running. But get it fixed ASAP!!

Let us know how you make out!!

 

Mine was built 8/04 at the KC plant. I had the ECM reflashed and it hasn't stalled since. I did have some scary moments when I lost all steering and brakes around a corner though.

 

interesting. I have a buddy that bought a truck exactly like mine and he had the same problem you did. Happened 5 or 6 times in two days. Not sure if it continues to happen though.

 

Mine required a new PCM to remedy this exact same issue. The reflash didnt fix it, the PCM was faulty. No issues since...

 

Mine too with 2500 miles stalls at least twice a day. Especially when coming to a stop. Even on the highway in rush hour.

I see that others have the problem, but I didn't see alot of fixes listed.

I've begun to wonder if the "diesel" sound tapping in the engine is somehow related?

 

It's definetley the ECM. For some the reflash fixes it, for others the entire ECM needs to be replaced. When was your truck built?

 

My new 2004 XLT SCAB 4X2 5.4 did this same thing. It stalled on me once at a stop sign. The truck was going back to the dealer to fix a small paint blemish. A service guy from the dealer called me to set an appointment and asked me if there were any other problems. I mentioned the stall and he said take it to the service dept before the body shop and they checked it out. They ended up replacing the entire computer and it works fine now. I really didn't think anything was wrong because it only did it once . I had to wait for the part to come in and a couple days later I received a courtesy call on my service visit. That night it stalled again in an intersection. So, instead of waiting for the post card I was told I would get when the part came in, I called the service dept the next day and the part was in and it was fixed. You are right it is dangerous and you might need a whole new computer like I did.
Good luck

 

BTW my truck was assembled in KC August 17, 2004.

Did your new PCM help your MPG? I had my o4 reflashed it seems to have helped it cutting off but the MPG is still 11.7.

Mine gets exactly what the sticker said it would get 14 city, 18 hwy. Didnt get to drive it much before, it started stalling within 3 days of delivery.
