Stalls while driving

Hi, my van stalls about 4 to five times a day. Usually going uphill or on the flat but never downhill. I turn the key off and put it in neutral and it starts right away and runs well for awhile. I have been to ford who said there was no codes and couldn, t help me.I went to a tuneup shop and had neww plugs and wires andnewfuel pump egr valve egr solenoi and fuel filter and fuel injection cleaned. It ran great for about 20 minutes and stalled again. So I wnt to a specialty shop yesterday. They checked everythin okand still no codes they say that its got to be the computer but wouldnt give me any guarantees. Its an expensive part and i, m not sure what to do. Can you helpme before I go crazy. Thanks :shock: :shock: p.S. It does, nt stall normally, it just dies instantly

Hi, no I dont have after market anti theft device or any cards on my key chain. I, ve even tried a spare key that I have and it made no difference. Do you think that I should bite the bullet and have a new pcm installed? Today my van was even worse. It cut out about 8 times at slow speed on flat roads and also on hills at high speeds. Thanks ron.P.S. Was rear ended about one and a half years ago and had a new tailgate installed but no problems up until now.

Hi, JUst went to my van to check if was any codes yet. Could not believe it, there is finally a code. Its p0174---system too lean [bank 2]. What should I be checking out. Ron.

Thanks steve, I will get a new pcm. Can I install it myself, I know how to physically install it but dueyou need special equipment to set it up?

Hi, thanks for everything. I, ll let you know whats hapenning in a few days. Ron :D :D :D

Hi Steve, finally found the problem. A father and son shop close to my house took my van for a week and gave me a courtesy car. It was the alternator. It was giving 14 volts to the battery and sometimes only 12 volts to the pcm which needs at least 13 volts to operate the engine. Runs great now. Thanks for all your help. Ron

I too am having the same problem but, I had my alternator checked it was fine so they say. Any advice on what you did to solve your problem with the alternator. Some are saying that it is the pvc valve in the back of the engine with an air leak, also did your engine make a funny noise coming from the belt side, kind of a sqeeking noise. Im going crazy with this.

I jave a 02 ford windstar that shuts off randomly while im driving sometimes it will only***** but others just completly shut off and as soon as I pull over and try to start it back up it will turn on I need help cant figure out what to do I have no check engine light so im not even geting a code any advice?

Oh I guess the bleeped yerkk. Hum I was thinking it could be the alternator and I notced this morning that my rpm sits below 1 like at half way to one. And when it turns off illl go to the shoulder and turn right on drive 10 miles and not turn off or drive a few yards and turn right off

My Van stalls when is cold coming to a complet stop at times, but when hot I dont have a problem.
I have replaced O2 sensors, MAF sensor, fuel filter, tuneup, fuel injector cleanned by professional. And I still have the problem and not engine light.

Did you replace the alternator or battery recently?

Hello,
no I have not replaced the alternator or battery recently. Do you think I should get it test it?

Thanks

No not that I know of. See my windstar stalls every 5 minutes. I just replaced alt. Just trying to fig it out.

I have the same trouble with my windstar. At first it would only stall during a stop at a stop sign, especially if the vehicle was in a slight incline. Now it stalls more often, even when I'm rolling in slow traffic. It's a pain, I could use some help here too.

2002 Ford Windstar 6 cyl Automatic 126500 miles

We had our battery and altenator replaced (Sears said it was a bad battery(only 2 months old), then checked the altenator and said it wasn't charging. They "fixed" it but on the way home it stalled on me (all lights on dash came on), felt like it wouldn't turn or stop either. Van started right up again, then did it not less then 1 mile later. Again van started up again. Now at another mechanic, they said initial check showed everythng was ok. But they are still looking.

Any thoughts?

Hi. This is a perplexing problem. My 2001 Windstar with 3.8 engine has started stalling intermittently without giving any codes at all. Not even any soft codes nor anything for the "flight recorder" for my mechanic. It idles fine. It doesn't stall when coming to a stop. It stalls primarily just after I have started from a stop light or turned a corner and I am accelerating in a normal fashion. Sometimes when I am cruising along it will "stumble" like it wants to stall, but doesn't. When it stalls, it doesn't die slowly (like being starved for fuel), the engine just shuts down like the key was shut off. It always restarts with no problem - don't even need to pull over - just put it in neutral, turn the key back and forward, and the engine starts right up. We have changed the fuel filter, fuel pump relay, ignition control module (coil), crankshaft position sensor, and lastly the power control module (PCM). Unfortunately, nothing has fixed the problem. The mechanic said it died on him just getting back to the shop, and even though it didn't give a code, he could tell that the injectors had lost ground on the negative side (or something like that). It never dies when going over bumps, so it doesn't act like a loose wire or connection. Any suggestions?
