F150 Stalls when put in gear

[BigRich123]

Hi guys,

My 2007 F150 occasionally stalls after switching from neutral to in gear and then giving it gas. It's an intermittent problem that's been happening for years. It didn't used to happen but once every handful of trips. Last weekend it happened three times though. The issue is definitely getting worse. Also at the end of last season, it happened while on the water except that time after stalling several times back to back, the engine wouldn't even fire anymore and we had to get towed. I took it to several mechanics but I'm still having the issue. I have the Yamaha software and plug. Any ideas?

This issue was solved. Follow the directions in the attachment on post #36

[rodbolt17]

the stalling at low speed is most likely a sync issue.
the no restart may be one of several hundred issues.
yds will typically tell you what is not wrong.
do a quick download and post it.
has the balancer ever been replaced on that motor?

[BigRich123]

I've never replaced the balancer. The last time it was in for service, the mechanic mentioned that he wanted to do it on the next service. I've also noticed more vibration now than when it was new.

Other than the injectors being clogged, I don't recall doing anything other than the regular service.

The download is attached as pdf for easier reading.

What's the idle at in neutral and in gear(idleing)?

[rodbolt17]

on the stalling.
have the linkage set following the latest technical bulliten.
the factory setting was wrong and so is the service manual.
back in o7 it took me about a half a day to figure out my F150 stalling issue.
3 yrs later Yamaha released a tech bulliten on how to do it.

if it is all done correctly you will have an idle speed of 700-750,a TPS reading of .7--.71 and an ISC request in the upper 30%to about 42%.

Is there anyway you can provide a link or make it available?

[rodbolt17]

if I think about it I do have a copy of the latest procedure from the advanced trouble shooting course last January.
I will try to post it.

[TownsendsFJR1300]

Mines running fine now (as I've previously posted), but that after a set of new TB's (under warranty) and another mechanic screwing it up.

After a couple hundred $'s, a Master Mechanic fixed it.. And I did show, before the TB's, several posts about how you fixed yours(the settings). Of course they ignored it...

I too would be interested in seeing it. My 2011 F150 has acted the same way since new (....and don't EVER try to tell a mechanic to adjust something according to an internet post.) I have developed throttle handling techniques that almost eliminate the stall. Now that I have retired and have the time I plan to do the adjustment from rodbolt's previous post. I have the repair manual, have brushed up on my digital multimeter skills and have been in the process selecting paper clips, a daunting task. One question I had was just how slightly to "slightly open all four shutters" to get it right. I assumed that would be a trial and error step.

[TownsendsFJR1300]

When they can't fix the issue or figure it out, I'm not going to tell them anything. I will however show them what I've learned here and what apparently works.

They put new, $1,100.00 throttle bodies on it, didn't fix it, etc. The other mechanic, I watched him, with a screw driver(trying to raise the idle) adjust a VERY NASTY VIBRATION into the engine (which they said is normal-the engine, idling, would literally walk itself to full lock). That's a "parts changer"

Once I found a MM, who was very knowledgeable, he was able to correct the issue apparently adjusting everything on the money. That was probably 3-4 years ago, idle is still dead nuts on, no hesitation, stalling.

The bulletin Rodbolt refers to I think came out AFTER my issues..

Rod if you need to you can e mail it to one of us and we can help post it to this thread.
Just PM one of us for our email address

today was crazy, I will try to dig it out tomorrow.
its dirt simple and can be done in 1/2 hour or so.

Ah ha! So, the tech bulletin says more than rodbolt says - I quote from his 12.05.2010 reply to High Sierra: "takes about 10 minutes and a digital multimeter." I forget where the paper clips came in but I have not selected mine yet so I'll wait for the tech bulletin if rod can get it to us - and thanks, I appreciate the effort.

the latest procedure actually has the air box removed and it uses the 4 channel manometer.
can be done without the manometer but hey I paid over 700 bucks for it why not use it.
kinda like my turn signals,I paid for them so I use them.

but it can be done without the manometer.

at the end of the day your looking for a TPS of about .7-.71V,an isc request of 35-42% and a stable idle between 700 and 750.
