Ford v10 stalling in the first five minutes

[ocean_bound]

I have a 2006 Georgetown Ford V 10 Lately when I start it Then head out It will stall in the first five or 10 minutes when I come to a stop sign Or light And restarts with no problem and does not do it after that Any idea what it could be And it runs perfect after that

Plugged fuel intake at the gas tank

Thanks for all the help and ideas I will start with the MAF Cleaning and go from there

2006 will be throttle-by-wire. The throttle body in them occasionally gets gummed up from PVC vapors, and can cause some stiction. But usually the first symptom of this is throttle lag at low throttle positions. The throttle-by-wire V10s do not have an IAC. Cleaning the MAF regularly is always a good idea.

Some of this depends on if this is the older mechanical throttle body with a separate Idle Air Control (IAC) valve or the newer electronic throttle body ("throttle by wire")

Cleaning a throttle body is a waste of time. The software is designed to handle "sludged" throttle bodies as long as the plate still moves. (I wrote some of that.)

IAC issues usually results in crank-no start (flooded).

Cleaning the MAF can't hurt.

My gut says it is a fuel pressure issue, but the only way to know for sure is to connect a fuel pressure gauge and drive it while watching the pressure.

Pre OBD-II

I thought OBD was mandatory since the mid to late 90's. I know I have used mine on Auto's and light trucks back to that era.

Correct ! I mis-read 2006 as 1996 ! Time for new glasses.

Check for "Pending Codes". The fault causing this might not be severe enough to trigger the SES light.

Two items that I would suspect, based on timing.

1) Evap purge valve might be sticking open, pulling too much vacuum on the fuel system. This may cause an intermittent P0452 code, but it only seems to trigger that code occasionally, even when the problem is continuous.

2) Heater on the forward O2 sensors might not be heating up anymore, so it's still over-fueling as it warms up. I've had this issue a couple of time. They only seem to last about 125,000 miles. Eventually it will cause a heater-open-circuit code but it has to get really bad before that happens. Earlier symptoms are what you describe, and may be accompanied by a pending P0133 or P0134 code (O2 sensor slow response).

Sometimes it's easier to diagnose by letting it get worse, although it's never a bad practice to make sure all your scheduled maintenance is up to date.

OBD-II has been standard on the E450 since '97.

I have no wires going to the throttle body so I would say that this is for a newer model year than ours which is a 99. The cleaning of both keep them clean but did not stop the issue. Just a good warm up and it was fine.

Try cleaning the mass air flow sensor and throttle body, then reset the throttle body calibration. Most likely it is the throttle body, but at least try a cheap $10 fix first to see if it solves the problem.
ALso probably wouldn't hurt to run some Seafoam in the gas every few thousand miles just to keep the system clean.

throttle body cleaning

MAF cleaning

Thanks everybody for the information I have a scan gauge up to it and it never throws any kind of code Throttlebody does make sense or mass airflow sensor maybe

[Home_Skillet]

I'm willing to bet it's the throttle body.
Mine was doing the same thing.

I was a Ford Technician for 25 years. I've replaced a ton of throttle bodies.

[MountainAir05]

Our 99 does it only in the cooler weather. I just let it warm up and slowly get up to speed and its fine. Never figure out why it does it and never a code.

[camperdave]

My van does that sometimes (1998 V10). Seems to be only after sitting for a while, I kind of think it may have to do with the evaporative emissions stuff but that's just a guess. I'm ODB2, but it never throws a code. I also have a 5 star tuner installed (love it), so not sure that's a solution either lol.

It may be time to flash the PROM. 5-Star Tuning may have the solution.
