- At 181,000 miles, there was certain misfiring going on. Very obvious when towing. The spark plugs were 80,000 miles old and the coils were original. Time to replace both and regain the 360 Horsepower I had before. Once done, what a difference!
Got a 2015 F150 5.0 this was a great video. I’m at 105,000 miles. Preventative maintenance is important. Most folks don’t want to spend money and cheap on on parts and maintenance and end up paying a lot more in repairs & or vehicle not making in to 200,000 miles or more. Who needs a Haynes repair manual when you have people like you😎👍🏻
I appreciate the comment. I agree, maintenance goes a long way in keeping vehicles for a very long time. And scheduled maintenance is almost always better than unscheduled maintenance, I say. Thanks for watching.
This is the first video that popped up when searching 2018 F-150 5.0 sparkplug and coil replacement. Just thought you might enjoy hearing that. This was the perfect video explaining it. 🤘🤘🙏🙏
Thanks man, I appreciate that. It started as a slow video, but eventually got rolling pretty well. Thanks for watching.
come on man that coyote engine is fancy! Just as fancy as a Euro v8! Thanks for putting the video up there.
Yes sort of if DOHC 32 valve is fancy right as opposed to pushrod, or is it just the 2000's and anyone with a pushrod is out of date🤣🤷♂. It's been a great engine from an otherwise marginal company. Thanks for watching.
Having exact issue on my 2017 F-150 5.0L with 87k miles. Stuttering "pop pop" at low rpm on both flat and uphill. When its "taxed" is the exact language I would use as well. Looking at purchasing coils and plugs now. I hope I have the same results as you. Thank you for posting and going into such detail. Much appreciated sir.
Yep, sounds like it. The more I paid attention to it, I found it happened on rough or smooth roads and only when I'd throttle it a little, so I determined with a quick and brief discussion with my mechanic that is was 95% chance coils and/or plugs. I mean it had been nearly a 90K miles on the plugs and the coils were original, so 170K /180K something, so figured I'd replace those. I'd go to RockAuto and see if they have good replacements. I went to AutoZone and they had Chinese stuff. My father-in-law went to RockAuto and got American made replacements. I'll be doing both again on my wife's Ford Flex coming up. Thanks for watching.
@@FloridaDeere Awesome. Good to know an thanks for the info. Ill be sure to confirm if it solves the issue. Will def be going with American parts 💪
Did it fix your problem
Change your throttle body! Mine did it
Great walkthrough of the process.I've had to do this a few times on different car engines. It's different every time. Thanks for sharing!
Yeah they are different, on my wife's Flex, it being a tranverse mounted engine, I need to remove part of the intake manifold, which is crazy to do spark plugs, so I'll just do coils then too. Thanks for watching Luke.
Same exact problem here. Replaced throttle body and it was the fix for me. Doing plugs as well just because they've never been replaced.
Yep, so far my TB has been okay, but I have heard of those going bad for sure. I'm approaching 202,000 miles now and hope to keep her running for many, many years, can't afford new truck prices😧. Thanks for watching.
My 2018 Ford F150 V-8 has at times ran a little rough over the last year for just a few seconds when I was going up a hill and I thought it might be bad gas or maybe it was time to change the spark plugs because I had about 75,000 miles on my truck. It only done this maybe 3 times a month so I was not in a big hurry to fix it. Then about 2 months ago my truck ran rough one night and the next day the check engine light came on and stayed on, but my truck was running fine. Then the light went off, but I decided to let my Ford dealer check my truck out and they said the engine was randomly misfiring on multiple cylinders and that the timing chains, gears, and guides needed replacing. I knew my truck had always made more noise than I thought it should and I had researched it and knew that the VCT system on these trucks caused weird noises and also caused some performance problems, so I let them replace the timing chains, gears, and guides. Ford never issued a recall on any of this and my truck was out of warranty, but I had told them about these noises and I told them I knew what was causing them, but because the check engine light never came on when it was under warranty there was nothing they could do. Well they fixed my truck and they charged me what I thought was a very reasonable price to do it, so I was happy. The truck ran better than I remember it running when it was new and it is a lot quieter and it shifts better. It ran great for a week and then it started running rough one night and I turned it off and restarted my truck and the check engine light came on and this time it was flashing. I was at a store getting ready to shop, so I turned off my truck and went in side for about 20 minutes and when I started my truck this time it ran perfect and the check engine light was off, so I drove 25 miles to get back home and my truck ran fine the whole time. I got to thinking and both times that my check engine light came on and it was running rough, it was sitting still and it had been raining when it happened. I need help if anyone has any ideas. I have done a little research and I think one of the coil packs is some how getting wet from the rain or high humidity and it is causing the coil pack to short out and when you leave it alone for a short time it dries out and then it runs fine. I also think that as long as my truck is moving, even if it is raining, it runs fine because the air circulation is preventing it from getting on the coil pack and that is why when it is sitting still and it is raining it starts running rough. I also think it is where the wire connects to the coil pack that is the area of concern. I am glad I fixed the VCT timing chain issue because it made my truck run better, but now I wonder if this coil pack issue could have been the problem all along. Any help or opinions would be greatly appreciated before I let the dealership look at it again.
Of course, every truck in different, but timing chains should last a good long time, several hundreds of miles in my opinion. I always go for the cheap and easy and seemingly simple fixes most times and se if they work. They are often the most likely many times. I had replaced the plugs around 100,000 miles, so it was a little early for those and on my 4.6L, I had a similar issue with coils, meaning once replaced, it was a huge difference and around the same mileage, so I figured what the heck right. I think it worked out. if your timing chain went that early, I would have been embarrassed to be Ford. I guess the engines are pretty complicated now, but there are some basic things to review before major repairs. I'm sorry i couldn't be more helpful. Thanks for watching.
Good and very throughly spoken. Quick question, the gap has to manually be set to a specific setting? Looking to do change mine on a 2019 F150 XLT 5.0
I think they come pregapped, but I always check the gap anyway. Thanks for watching.
How about showing how to release the plugs from the coils?????? The red sliders are completely out on my truck and it still doesn't come off
Yeah, no doubt that was the worst part of the whole job, I busted mine, at least a few and spent the most time on that issue. Everything else seemed to basically go as planned for the most part. Thanks for watching, wish I had a better hack for that part for sure.
I'm getting ready to change the coils and plugs myself, I've heard coil 3 is different but I didn't see this on your video? Is this true and any additional information on changing or should it all be the same?
I don't remember any of the coils being very different from the others. The rear ones are a little more difficult to reach and maybe #3 has an obstruction in terms of fuel lines or something, but it wasn't largely different from the rest of them that I can recall. Thanks for watching.
I just checked under my hood and my 2018 5.0 f150 looks completely different on the passenger side.
@@aaroncounts6657 Oh you have at least a Gen2 Coyote maybe even a Gen3, mine is a Gen1, so they could be different for sure.
Just wondering if you got a check engine light come on after this happened? The reason I ask is that I just experienced what you described, with what seemed like a bumpy section of a previously smooth stretch of road (duh!), then later that light came on, code reader showed P0351, which is a "Ignition Coil "A" Circuit Primary/Secondary Malfunction".
Nope, I never got a CE light oddly enough. Mine is a 2013, not sure if that matters, maybe yours is newer or older and this particular issue would trigger it. I just recently did them in my dad's 2007 and he had one and it went off after we replaced them. Thanks for watching Martin.
The anti-seize is a little thick on those plugs, no?
It does look like the one on the all the way right side got a little extra, but even so, I guess I don't see the harm. Thanks for watching though.
FYI NGK plugs do not require anti seize
Motorcraft the way to go from my experience
Yeah, it seems like none of them are cheap, those coils are pricey. Thanks for watching.
Does your 5.0 have the typer writer/ bbq tick?
HAHA, I had to google that, never heard that before, found a site that had a video. It was a Mustang video and site, but I'm 99% certain I have never heard a sound like that from my engine. I've heard other sounds, but that sound was very intermittent, literally like you said a typewriter sound. Thanks for watching.
Did the new coil packs and spark plugs resolve your “bump”? What you described sounds like torque converter shutter?
Yes the coils and plugs, probably the coils were the issue, no studder at all afterwards and much less downshifts and no hesitation with the new items. If that didn't fix the problem, I was headed to transmission diagonsis next. Thanks for watching.
@@FloridaDeere My 2017 with 127,000 miles is experiencing what I thought was "torque converter shutter", but watching this video and reading the comments makes me think I should try replacing the coils. I changed my spark plugs at 97,000 miles but didn't do the coils. Is your issue still resolved since the replacement? Thanks for the video.
@@nealparish4186 Yep, teh truck runs fine since the change, it was 100% the coils and maybe spark plugs too, but they had been changed before. I'm sitting at 190K miles now. I'll be doing a full front end replacement soon, like new coil overs, arms, rods and ball joints to a nice aftermarket OEM replacement that can be greased. Lame Ford and others have this stupid "lifetime" stuff without greaseable points. My old 2002 had greaseable zerks. It still runs fine and isn't urgent, hoping to get to 200,000 miles. I will even replace the front wheel bearings. The truck is a keeper, so I need to keep it in top shape. Also, I have switched my Ford content to "My Three Ford" RUclips channel. If you were curious about further F-150 videos. Thanks for watching.
@@nealparish4186 might just be coil boots, usually spark plugs and coil boots changed out same time
Do any of y’alls transmission make a hard shift from 3rd to 5th gear? I have the 10speed. When I put it in sport mode it shifts fine.
I don't have a ton of knowledge about the 10 speed other than it doesn't seem to be as reliable as the 6 speed and I had the 6 speed. Sorry I couldn't be more helpful, the 6 speed is very smooth, no crazy shifts.
My question is when you pull the coil packs off is there anything that's sitting on top of the spark plugs that I have to unscrew I'm doing this for the first time Ford did them and all of my coil packs are leaking oil
Hmm, that sounds really weird, I mean coil packs should leak oil. You unscrew the bolt on top of the coil pack and then the bottom of the coil pack goes over the top of the spark plug. The coil packs don't come into any contact with any part that has oil that I am aware of. Now maybe the spark plug isn't tight and oil is getting up through there. But even that should be a small amount of oil, nothign that should reach the coil pack really, at least I wouldn't think. If you want to send me an email with a picture so maybe I can understand it better, you're welcome to. Thanks for watching.
thanks
No wires ????
What do you mean no wires?
Did you buy the coils online? If so, do you have the link? Thanks for the video
No sir, I bought them from AutoZone, but I think you could probably get them cheaper online as I understand it. Thanks for watching.
Nice
Thanks for watching.
I'd spent the money on new plugs boots vs coils. These coils RARELY fail, but the boots deteriorate and cause carbon tracking.
Ha, I didn't know you could replace just the boot and not the whole coil, I bet that is a lot more cost effective. I'll have to look into that. Thanks for watching and the new info.
@@FloridaDeere just bought a set tonight on Rock Auto. $60 I think with shipping. No Motorcraft so I got the AC Delco.
BTW, never buy aftermarket coils. These trucks eat them in less than a year. MSD, Accel, etc, junk.
@@djwilson48625 I can't remember what brand I bought here, but when I did my Flex just recently, I used AC Delco as well.
Didn’t show how to take the clips off with the red tabs
Opps sorry, they just slide, you don't actually take them off. Although, if you get all eight off without breaking at leat one, my hat is off to you. But if you break one it's not the end of the world, they still will slide back if not entirely secured, the plug generally stays in if I'm not mistaken. Thanks for watching.
1:23 omfg everything u say is happen to me right now i was thinking the same too but I don't have the engine light and I just reach 100,000 milles
Yeah, I may do the coils again when I do the plugs, or maybe at least test each coil if I can. They are certainly a lot pricier than plugs that's for sure. But it was an easy fix for sure. It now has 208,000 miles and still runs pretty good, no real complaints except the A/C system on this Ford. All my other Fords, never had the first A/C issue, this one has been less than average in that category, otherwise this truck is pretty solid. Thanks for watching.
Yep clean first!
This engine just passed 196K miles and saw lots of towing this week, I like to keep my stuff well maintained, because I certainly use it hard. Thanks for watching.
Bidenomics
I don't think I follow you there man...
