Truck has started to die after a stop and then take off

[wanted33]

@D Fresh, IDK Doug, with this wording it looks like he's describing the Auto Start/Stop to me. Maybe we can get the OP to say for sure.

However, the (engine)stalling out after stopping
then (engine) starting to go again is something I cant tolerate.

If your ASS engages after stopping and starting to go again, you should get it checked out, it should never engage with the vehicle moving

It's all matter of how you read it. Op has ghosted us anyway. We'll likely never get clarification.

You're right, it can be read a couple ways. I edited my post to help see how I read it. Oh well, we may never know.

was it stalling or just turbo/throttle lag?

Stalling.

Maybe we should stop diagnosing his issue by speculating on what OP is really trying to say.
There's 24 replies, but no further input from OP. Maybe its not really as big a deal to him.

He probably realized it’s the ASS and was too embarrassed to respond. It’s okay, we’ve all been embarrASSed by the ASS.

This does not sound like ASS to me?

OP: "Love the truck if it didn't stumble and now started dying. Sometimes it dies die it just looses all power for 3 seconds or 4 and then picks up all of a sudden and recovers good and strong."

I’m just here for the laughs. It has delivered.

I'm sure this has been talked about and if so please forgive me. I did search for this particular topic and I got a ton of results and fishing through several didnt find anything specific.

I have a 2020 Ranger , just turned 30k on the odometer. Like alot of people it had the stumble when shifting which I've learned to deal with. Dont like it but learned to deal with it.
However, the stalling out after stopping and then starting to go again is something I cant tolerate.
Does anyone know what is causing it and have a fix.
No check engine light. No pending codes but I have an old actron scanner. So there's that.
. I am the second owner at just 30k so I'm assuming someone else had some issues and got rid of it.

Since owning my truck, I've had 3 instances where it felt like the engine stopped. The first 2 times, the engine just felt like it wasn't running, the last time was accompanied by a shudder. I've tried to purposely replicate but can't seem to do it on purpose.

I have an ASS dongle with it set to off so it isn't shutting off because of ASS. In any event, I'm never at a complete stop so it shouldn't activate anyway.

In all 3 instances, I go quickly from brake to throttle to brake to throttle at low speed, almost stopped. So, for the latest incident, I was following another vehicle and approaching a yield sign. I'm on the brake at low speed. The lead vehicle stops, then goes. I am still on the brake and moving slow. Once he leaves, I blip the throttle to get to the intersection quicker, and lightly apply the brake. I'm still watching the lead vehicle to be sure he doesn't change his mind. Once he leaves, I check for traffic, and then on the throttle once I see all is clear. That's when the truck feels like it dies. After what seems like forever, the truck shudders slightly, and then goes back to acting normal. To be clear, I don't think the engine died and all of this happens in just a few seconds.

The other 2 incidents were similar but without the shudder.

I thought maybe that with the throttle blip, the turbo started to spool up, then blows off when the throttle is closed, and then has to build pressure again in a very short period causing hesitation. I have no idea of why it shuddered but really can't see this as a transmission gear hunting issue since the truck is moving very slowly. And, I don't think it's worth having it checked out since I have no codes and can't replicate. I've pretty much accepted this as a quirk.

The OP may be experiencing something similar. I don't know if his vehicle is actually shutting down or not, but it isn't necessarily the ASS.

yes you're definitely sounds turbo related....all factors combined, you caught it in a bad moment of its power cycle.

Agreed. I solved my issue of power loss when passing traffic with the peddle pushed through the floor board to pass. Truck would fall on it's face and lose all power to the point that I couldn't pass. Same issue on my 2014 F150 eco. On both of my trucks it was excessive condensation from the intercooler. Does a fantastic job with cooling the charged air but to the point of heat cycles that water builds up. Resolution, drill a small weep hole in the bottom of the intercooler so the condensation can drain. Not the perfect world, but it works. I do get oil residue that I have to wipe down from time to time. I would rather do that than die in traffic, lol.

One other thread that I recently read was water in the EGR that was creating the issue as well. I haven't checked mine however, my issue has not returned after the weep hole was drilled. Now stalling directly after an auto stop and restart with out a heavy acceleration then I would tend to agree with the auto stop being a problem.

Thank you for this fix I will be drilling a weep hole as soon as I get my 2020 back from the dealer. I know about the catch cans but like the simple solution. Went into limp mode and was told there was water in cylinder 1. This is becoming all too common and Ford needs to address the real problem, not by adding a cover.

Are you losing boost here?

 

[Stangman570]

Are you losing boost here?

Nope. Follow the f150 eco procedure for the size of drill bit. It's not a large hole, just enough to drain the condensation. Will you get weeping of oil out of it, yes but it's not alot. Just wipe it down between oil changes and you'll be fine.

Just looked at the "fix" you are definitely going to be losing boost, that's intake air post-turbo. If anything this is just masking the symptoms of some bigger issue and reducing the effectiveness of the turbo.
