Ford F-150 stalling at idle - What’s your thoughts?

[@NJ-or4qr]

PLEASE READ!!! Don’t know if your issue has been fixed, but I had the EXACT same issue a couple years ago with rough idling/stalling on a 2016 F150 XLT with 5.0L V8. After many months of trying different things, I talked to a head mechanic at local dealership, it is your VCT solenoids. He recommended to me to switch to motorcraft synthetic blend oil AND filter, but not only that..he said “I know you will be spending more money, but change your oil more frequently.” (Every 3500-4000). I have done EXACTLY that for the past year and a half and have not had ONE sliver of rough idle since. I’m no mechanic but the way I understand it, when your oil life gets low, it can effect your VCT’s especially if you’re not using motorcraft oil and filter. The guy told me that the motorcraft filter helps to keep your oil running cleaner than other filters. Yes, at the time when he told me this I thought he was blowing smoke but I was desperate and fed up with my truck at the time. So I tried it and have not experienced an issue since. I apologize if someone has already mentioned something similar, I haven’t read through all the comments

[@NJ-or4qr]

And just to add to this to all who read this, mine started doing this early..maybe around 45-50k miles. And did it for a couple years up until around 80k or so when I swapped to all motorcraft and changed my oil more frequently. I am now around 110k on the truck and have not had any rough idle or stalling since around 80k. And I have not touched a VCT solenoid or any other parts

[@andrewdicks627]

When your truck stalled out did it roll backwards slightly? And even in drive it just died? My 2015 f150 just stalled out like this and the dealer can’t find anything wrong with it.

[@NJ-or4qr]

@@andrewdicks627 nah it never did that. Mine was only at idle when I was completely stopped. Would idle rough and it got bad enough several times where it shut engine off and had to restart truck at a red light. Have you had rough idle issues that have progressively gotten worse or was this the first time this happened? That sounds like maybe spark plugs to me? Idk. It would also mainly do it when it was really hot outside or if I had been driving for a while and engine was warmed up

[@NJ-or4qr]

@@andrewdicks627 just read over your reply again, not spark plugs lol but yes in drive it would die when I was idling sitting at red lights or stop signs. How long has it been since your last oil change? And what kind of oil and filter have you been using?

[@NJ-or4qr]

@@andrewdicks627 also to add to that, I’ve read forums where dealerships can’t find anything wrong with some of these truck because it’s not throwing any codes. Apparently if your oil life gets low enough it can start rough idling and throw codes when engine is warmed up. But it’s harder to recreate it at dealership especially if the truck hasn’t been driving for a while with engine warmed up properly. So to put things in simpler terms, if you use the oil and filter that is recommended for your f150 and change your oil before your oil life gets to a low point, doesn’t it sound like it would negate all the rough idling and stalling issues? I’m just trying to recommend what has worked for me. I’m no mechanic, but whether I’m just putting a temporary bandaid on an issue that needs to be addressed (VCT’s and cam phasers) or if I’ve fixed the issue from better maintenance habits is beyond me. But the truck is holding steady for almost two years now

[@stevepowell4444]

That oil pressure gauge on the dash is a dummy light. As long as the pressure stays above whatever Ford's minimum spec is, it will stay in the middle of the gauge.

[@stevepowell4444]

@@robinsonsauto yep. I had a 2004 Explorer with the same setup. Very frustrating, I was always wondering in the back of my mind how the oil pressure was. In the end it didn't matter, the timing chains were getting pretty noisy and then the tranny died. Started slipping on me and I was able to limp back home but toward the end of the drive I couldn't get above about 20mph.

[@justforkiks29]

Check oil pressure after a good drive when it is hot. If less than 25psi replace the engine. They are notorious for eating up cams and cam caps from low oil pressure. Even with new oil pump and timing set it can not maintain oil pressure at idle which causes the P0022. Pull a valve cover off and remove one of the cam caps to inspect for scoring.

[@Hurlburton]

Been watching this channel for 14 years Always something new to learn

[@Steve-bj2se]

What bothers me is the negative LFTrim both banks. This normally means restricted air flow thru the engine. Wife’s ‘03 F150 had been stalling at red lights for years. One day I asked her if she had ever replaced the air filter NO. Drove it to auto parts and replaced air filter. The old filter must’ve been original. It was noticeably heavier than the new filter and was packed full of dirt. I should have caught this earlier. Not my intention to throw her under the truck!!! Sounds stupid but honestly this fixed the stalling problem.

[@SteveRobReviews]

Willy I fixed lots of F150 intermittent stalling , no codes only stalls at idle speeds . Evap purge valve sticking open. Watch the open/closed on the purge valve . Oil pressure on a Ford is a on /off not an actual reading .

Hey Steve thanks for the feedback.. this was my initial thought but Ford beat me to it.. they fitted a new purge valve when they had it. New doesn’t mean good though lol

Wonder if anyone came up with a resolution? I've got a 2016 5.0 that is doing the exact same thing. It's to the point that I put one foot on the brake and the other foot on the gas pedal to keep the RPMs a bit over 600 when I'm at a stop, or more often than not it will stumble over and over, and sometimes eventually die.

[@markcrisp5944]

Same problem 2017 f150, it’s a shame this hasn’t been recalled.

[@spelunkerd]

Oil pumps are volume driven, so any cause of low idle will cause oil pressure to sag at idle, and low idle can cause stalling. I'd be looking at things that affect idle, clean the throttle body, have a look at IAC counts if there is a data pid for that. It could even be that the cam phasor isn't getting enough oil pressure to move properly, so fixing an idle issue may solve everything.

[@robinsonsauto]

Thanks for all the great suggestions, I was initially hoping for the same. then I noticed the actual vs desired RPM in both captured instances.. nearly spot on. and the desired RPM while monitoring the oil pressure are very close as well.. when this did act up on me I noticed a slight hunting in the tack prior to it shutting down, I grab the scanner as quick as I could but I missed my window... I noticed the purge was commanded around 18% I'm also trying to look up the theory of operation on how the phasers interact, during this cycle and the idle operation. there's no IAC

I have the same truck right now and it’s doing the exact same thing you cannot put low-grade gas in it. It is a gas problem. The engine does not like it. I have a ethanol engine when you use ethanol it never does it because it’s the octane in the regular regular gas. I have to add fuel additives to mine from the place I get the oil change and the problem goes away. It got to the point it would stall out when I was in the middle of an intersection as it got worse and worse.

[@srlbombboy0127]

What fuel additive did you use? I’ve been having the same issue but like you said running higher octane makes it go away for a few/ was it a one time use or are you using it every tank?

[@deadman12078]

Had this happen with my 2003 Chevy Silverado. When coming to a stop... Like when pulling in to a store or a light the truck would just stall. Not always but random. Other times RPM's would drop to below 500. All I had to do was clean the throttle body. Less than $10 fix with throttle body cleaner.

[@robinsonsauto]

Thanks man, I will do a follow up soon. This is one proactive step I took just to rule it out.

[@thomasjefferson6334]

Really?? I thought for SURE it would've been the Idle Air Control Valve needing to he cleaned

[@kj197734]

Probably the primary failure is the cam phaser at this point. Secondary failure is the VCT. Oil pressure is the key. Ford threw parts at these like the PCV, oil changes, air filter, reflashings, spark plugs, and the purge valve with no improvements. I could be wrong of course but good luck it isn't too major.

[@robinsonsauto]

I have a bad feeling your onto something.. I'm hoping to have the truck back soon, I was able to do some basic things giving the time we had with it...

Ivan just did a video on a Subaru with a similar issue. But in case the car would stall when you turn on the headlights. He traced it down to a bad ground. This type of work can be time consuming, frustrating but rewarding too. The oil pressure concern is valid. It would be nice to know if the Ford engineers have a engine shut down strategy for low oil pressure.

[@robinsonsauto]

Thank you for the feedback Wyatt.. been wanting to check out that video. Ivan is a great guy. Seems low for a VVT on these fords. I read something about this a couple years ago.. maybe that’s why I’m stuck on that. Along with the P0022 showing up twice at idle.

[@janicewilliams2194]

What about a fuel pump or a fuel filter in the tank?

[@Pantha-ny6hl]

I had a stretched timing chain on my 2015 3.5 ecoboost (130K miles). I changed the tensioners, chains, phasers, and 4 vct solenoids and the truck still stalled. I had to clean the throttle body, reset the ecu capacitors (remove negative batt terminal, then connect small wire to + & - for 10 minutes), then do the idle relearn procedure. My truck idled like crap at first, but I let it idle for 45 minues after sitting overnight to relearn idle correctly from a cold start with all assessories "off". Now my truck idles like new and never stalls. Don't forget to recalibrate the throttle pedel also after to maximize your throttle response. Lastly, keep your oil changed with high quality oil every 3K or so miles. I hope this helps someone!

[@bdubblin]

So I have been chasing a stall at idle intermittently. What I noticed on my data is that vct intake bank 1 was stuck at 0.0 advance. while the bank 2 side was at 20 degrees advance and bank 2 would fluctuate when operating the engine off idle. Bank one intake will not change...stuck at 0.0. The exhaust vct would be at or near 0.0 advance at idle...which is desired. both intake vct should be at 20 desired. No codes will occur even after one week of driving with intake at 0.0 advance on vct read out. With an oscilloscope attached. I get normal waveforms from bank one intake vct..... makes no sense...right?

[@TheOmegaman69]

Given the limited information available from the video, I would ask the customer if they just got an oil change when the problem started. You see the oil pressure is low, and 15PSI is low. First thing I would do it make sure the oil is full, clean, and just as important if not more so (in this case) is if the correct viscosity oil was used. I would also ask the customer about the viscosity of oil they use. An incorrect oil viscosity can cause this exact problem you are having. Testing the oil would possibly help, but too time consuming and expensive.. Maybe, hopefully, this is helpful.

[@robinsonsauto]

very good thoughts! its almost as if you were reading my mind. I reached out earlier with very similar question as to when this started and if it correlated with the last service. they believe it started prior and are looking into it deeper..

Funny thing is I change my oil ever 4K miles at the dealer. So I know that’s not the problem. The only thing I can think is could you somehow tell the truck when it’s at idle to idle above 600rpm. Seems like it only jumps when it’s below 500rpm. It’s the weirds problem. Put new spark plugs new ignition coils. If you find a fix tag me.

I change the oil. And put the right gas in it. Drive it for about 3040 miles, and it Completely went away. As the oil gets older. And I start sneaking and putting regular gas instead of higher octane to try to save a couple bucks. It will come back. Probably in a couple months. I know I shouldn’t do that. But gas is expensive. Put high octane or ethanol in and it goes away again. Just saying.

[@taylormurphy5221]

The drivers intake VCT solenoid is not happy. Since there's no P0020 code it's mechanical not electrical. If oil is good now and issue persists, you can most likely deem the solenoid bad. If he only changes the oil when the truck tells him to or later, these things get gummed up, then camshaft stays over retarded. I had same symptoms and the same code, but also the electrical code as that was the issue. I have a video for testing the resistance, but I don't think thats the problem here. You may hear an audible difference in clicks if you can supply voltage to the solenoids. Ford oil pressure gauge is a dummy gauge. As soon as it sees like 5 pounds it reads full and stays there.

Wonder if anyone came up with a resolution? I've got a 2016 5.0 that is doing the exact same thing. It's to the point that I put one foot on the brake and the other foot on the gas pedal to keep the RPMs a bit over 600 when I'm at a stop, or more often than not it will stumble over and over, and sometimes eventually die.

Same issue here on my 2016 5.0 did u ever fix the issue?

[@NJ-or4qr]

@@jeremyruss2407 check my comments I just put up on here, I have a possible solution for you that fixed my same issue

[@danman9017]

i would clean the trottle body > do a clear kam > do a trottle body relearn procedure and see how that goes

[@robinsonsauto]

If I can’t prove anything out this will most likely be the proactive approach I’ll take. Thanks for the suggestion

[@danman9017]

@@robinsonsauto if the battery was disconect it could lost it idle learn i have seen it on the 6.8l stalling because battery was disconected ,but the ait is hight for me in winter do not know the temp over there .mabee intake hose is crack to trottle body ,but a visuel inspection is a must before diagnostic

And mass airflow sensor

im feelling the dealer techs suck or rather their experience sucks, they are usually pretty young but one would think, known problems get passed down as knowledge especially at a dealer when thats all they work on. eric o at south main auto gets dones of vehicles that have been to the dealer or other shops and he nails every time. no matter make or model.

Vct solenoids and oils change

[@robinsonsauto]

I have a feeling but I’d love to prove it out somehow.. hate when it’s intermittent

[@reallife2849]

My daughter had this problem with her Subaru treck they carbon cleaned the engine, changed vct ,changed oil , and intermittent came back and changed o2 censors . everything is good now. A real problem with bad idle and dash lights all on . Goes into limp mode . Think it was all faulty o2 censores

[@Eric.schmidt]

@@robinsonsauto spent many years as an auto tech till I hung my wrenches 20 years ago. So hard to prove intermediate issues. You saying it was due for an oil change kind of helps show that’s the direction to go though

[@TwistysGunShow]

It's your cam phazer and vct solenoids

[@rogerrabbit8756]

I just replaced both and when I picked truck up it stalled within 4 minutes.

[@TwistysGunShow]

@@rogerrabbit8756 I'll try and find my receipt ,they ended up changing a bunch of stuff. Mine hasn't stalled in over 15,000km if I can find it I'll send you the list of parts

[@rogerrabbit8756]

@@TwistysGunShow thank you! I left the truck there today after not making it out of lot. Another tech thinks it may be the intake runner but who who's at this point.

[@rogerrabbit8756]

@twistymcbudz6786 I paid 6k crazy, chains, phazers and the 4 solenoids,.plugs ect.

[@TwistysGunShow]

@@rogerrabbit8756 yeah they ended up replacing the intake runner in mine after but it wouldn't make mine stall it would just go into limp mode when I would lay in the throttle hard and I had engine light on . Mine was 12,000km after warranty but they covered it because they knew it was messed up long before warranty was over, mind you I had to threaten that I would take them to court or burn down their shop 🤣 it sucks you had to pay out of your pocket because ford knows their product is shit . Even though my truck is fine now I will never buy a Ford again and I've been a Ford guy for a long time

The problem is you've reached 60k and it's an Ecoboom.

[@dm7097]

I’ve heard that ford has (for a long time) made their gauges act like only switches. I.e. either on or off, not actually giving out readings. Kinda stupid imo.

well ya it had 600 rpm. likely wasn't while driving

[@reallife2849]

Too much emissions. Time for carbon cleansing. Throttle plate tolerances are tight clean the back of its hard to tell , China cams are soft and self destruct

[@robinsonsauto]

I will definitely give this a shot, Won’t hurt. I’m really concerned with how low the oil pressure is at idle. I’m starting to think when it goes through a cycle one of the phasers are hunting or both? Wish I could recreate it. It was really bad. Then just clears up. And will be ok for a little.. definitely getting worse

[@aikinkai]

Just got back 2019 F150 5.0 V8 for stalling at idle. Starts fine, but after coming to a stop (I.e. stop light, stop sign), would have trouble maintaining idle and engine would shut off. Local Dealer applied TSB 19-2365 (static.nhtsa.gov/odi/tsbs/2019/MC-10169811-0001.pdf) which corrects High Intake Manifold Vacuum during deceleration which results in oil being pulled into combustion chamber. Basically..it burns a ton of oil without any visual residue resulting in low oil. This corrected stalling problem immediately.

[@rogerrabbit8756]

Still no issues?

[@jasonjoncas-l2g]

Fix the cause not the effect 5 k oil changes 3.5k in the states this issue is 100% of the problem lack of clean oil times have changed today the passages are small and feed the cam phaser . Any lack of flow will reek havoc and cause issues as in neglected oil changes. You want to have it years to come I have a 2007 5.4 3v 200k yeah metric and quiet with original cam phasers bough in 2010 gave it to my son 2024 still quiet and the spark plugs come out ha ha. Now have a 2017 no bullshit a 5.0 got over the bucket of marbles this sounds like at idle thrash it like my 2007 this thing is way more fun. The lack of a limited slip axle sucks because using the e locker on dry ground will explode it. Anyways change your oil every 5 metric k advice from a old fuck 58 years old that started pulling wrenches out of the womb in 1966. Hell if I found a screwdriver the Christmas toys would come apart.
