Ford F-150 (2009-2014) :: Loud Noise Coming From 4.6 Motor / Missing
Apr 24, 2017
I have a 2010 ford f150 with a 4.6 engine. it has developed a loud noise like a diesel on steroids and also sounds like its going to fly apart and it also misses when it does this . now this is how I have narrowed it down to make it happen because it does not do it all the time. it mainly does it to and from longer trips like 45 minutes or more then coming into traffic to a crawl or idle it will start making the noise . also when I pull into my drive and go from drive to reverse and go to back up it will also make the noise. I have no lights on the dash or codes. could this be a coil pack ? I had a coil go a few years back but it acted up under load on a hill and just missed with no noise.

2012 F150 6.2L V8... I am at a loss and I know that loud knocking is not a good sign. Two days ago my truck's low oil pressure light started coming on and off, so I pulled over and immediately turned my truck off. I called a friend at a Ford dealership and he asked a mechanic what I should do. He said it could be something as simple as low oil, bad oil sending unit or maybe something serious. So, he said check my oil level if low top it off and see if that fixes the problem. It was low and I topped it off, but the light kept doing the same thing.
Here's my dilemma; my truck wasn't making ANY noises (knocking, whining, etc...), 2 days later which was yesterday I was en route to get new oil/oil filter changed and 24 miles later I'm in a turning Lane and it dies! Will not start, but it tried, so I did not try anymore. I was able to get it into a parking lot and left it for about 4 hours and went to check on it and it started right up and that is when the knocking noise started. I turned it off and checked the oil and the level reads full...

Driving the wife's 150 EB today and is it just me or is the noise made by the turn signal relay really loud??

The turn indicator is annoyingly loud? Does the small speaker under the dash make all the tones for dash functions, including the blinker noise? I'm tempted to put a piece of sound deadening foam over that little sucker.

Today I was out getting lunch in my Ecoboost When it started making an extremely loud grinding noise from the front end of the truck. My first thought was I blew a turbo. After holding the break and building boost I discovered it was not the source of the noise. Also the truck runs perfect and there is no smoke. I then took it to my friends auto shop and pulled both front tires off to check and see if anything break related came loose. We found nothing. The noise only happens upon acceleration or cruising throttle, as soon as you let off the sound goes away. So after I found nothing I took it to ford and what would cause that, but they assured me that they would have my truck for a long time while they figure out the issue.

Just had my 2010 F150 in for a loud knocking noise when the truck has warmed up in drive and rpm up to about 800. I can't hear the noise when I disconnect the passenger side vtc selonoid. The Tech who worked on it has recommended replacing the motor. His troubleshooting on the ticket says he removed the coil from the number 4 cylinder and the noise he hears goes away. I just can't see that the motor is bad.

Whenever Im driving at slower speeds - parking lots, side streets, etc I get a squeaking/squelching sound coming from somewhere in the front end of the truck. I thought at first it may have been a rattling heat shield someplace under the truck, but now Im not so sure. No loss of power, check engine light, or anything of that nature has occurred so Im not sure what to do. Its a 2010 Ford F150 XLT 4wd ....

2011 XLT 5.0 Coyote. Truck has a performance problem - it's missing almost unnoticeable at idle, but it's obvious (if you care to notice) when you hold the throttle barely open. Idle seems smooth, but if I hold it at about 1500 rpms, it most clearly and definitely is missing.
However, since there are "no codes" and since mode shows "no misfires". This really manifests itself when I'm towing a 6k pound trailer and the truck can't pull it up a 2% grade unless I drop it into 3rd gear. Of course, if I drive it like a race car it's a beast. But I can't leave rubber at every red light, especially when towing.
Fuel trims look fine (ST bounces between -4 to +4, LT sits right at +0.5). Cleaned the TB. Cleaned the MAF. Brand new Motorcraft plugs gapped at .045. CHT sensors read 205 on one bank and 198 on the other. Coolant sensor seems find. Haven't done a voltage test, but TPS data in the OBD seems smooth.
How to test the coil packs (neither does Ford). They want me to replace all 8, but I'm not doing that unless I can see real evidence a coil pack is bad.
I'm no novice however I'm losing my mind that "everything is normal" yet the truck so clearly has a problem. This has been going on for months and I'm at my wits end.

As I was driving home from vacation the other day while towing my boat I started noticing a tapping sound coming from the passenger side. Sounds like an exhaust leak or a lifter. Can't tell. Sounds louder under acceleration. It's a 2009 5.4 with 70k. Just had ford do oil change last week. Oil level is good.

Experienced noise coming from the temperature control unit? I generally hear it immediately after turning on AC or Heat and then when I adjust the tempature up or down. It only last for a few seconds then goes away. I plan on taking it by the Ford dealership. 2010 F150 Platinum...

My 2010 F-150 has a vibrating noise that seems to be coming from within the dash. The noise starts around 40mph to 50mph. It stops if I let off the gas or I accelerate. I cannot figure out where or what is causing this.

Faint humming/whistling noise coming from the drivings side of the motor. I can hear it when I put my head next to the drivers wheel well, and most certainly from that side of the motor when the hood is popped. It's not super loud, but it is noticeable. I know we have Direct injection motors, so I know that ticking is completely normal. Am I overlooking this and being paranoid? Car has 2100 miles on it. I don't know if it was there when brand new.

I have noticed recently that I have a "rubbing" noise and vibration coming from the right front wheel on my FX4. It is most noticeable from 5-10 MPH, and more pronounced when turning right. it is not constant. It sounds almost like a brake pad rubbing on a badly warped, wet rotor. It goes away when I apply the brakes. I am thinking bearing or possible CV joint.
The dealer can't get it in until Tuesday, and they say I will have to pay the deductible on the ESP, even if it is related to the steering vibration they could not replicate or fix about a month ago. I am seriously considering going to another dealer for my service. Given, they did absorb the deductible last time, but they didn't fix the problem!

The other day my left light went out. I ended up taking out the sockets and realizing that it was the green wire that goes into the socket. I fixed it and it worked for a while and now both my lights went out. Hi and low. Every time I turn my light on I hear a weird click noise coming from the fuse block. It sounds like a bad relay. What it is?

i own a 2010 corolla s with only 3000 miles on it. it is a 5 speed and the other day, when revving out 3rd gear to 5500 rpm, my motor started missing, and my check engine, vsc, and trac control lights came on. i turned off the motor and then started it back up and it ran fine but the dummy lights stayed on. i took it to the dealer and they check the codes and it showed that cylinder 2 missed. after explaining to them how it happened and taking a service technician for a ride, they took off the valve cover on my motor, and seen that 3 rocker arms had FALLEN OFF and they tried making me pay $700 to fix it because i was "over revving the motor". I was told that the rocker arms cant withstand that high of rpms and they will fall off due to the floating design "not bolted". but after 2 hours of arguing, they said they would cover it, but only this 1 time. I don't understand why they have the rev limiter set at 6,300 on these cars, when the rocker arms are capable of coming off at 5,500.

My 2011 F150 5.0 was bought used a year ago, and ran like new. A few months ago, several things started acting up.
* clicking at idle. Just a tick-tick-tick-tick kinda like a diesel. I swear it just started, but the dealer tells me it's "normal".
* Oil - I'm "losing" about a half quart a month. No leaks. 1500 miles after a change, it's dingy. (not dirty just brown) Dealer tells me it's "normal" that these trucks consume a little oil and that it will get dirty.
All that I could ignore but this is what bothers me:
The truck seems to struggle, mildly, to maintain speed on hills. It'll drop to 1k rpms before downshifting. Just a pig. Of course if I stomp it to the floor I get a good response, but it is just sluggish and wimpy when driving "normally". Also, when maintaining speed, there's a barely noticeable missing/slipping happening. When I pull a couple thousand pounds it really struggles.
This is happening. Three dealers tell me there's nothing wrong with the truck. After pressing the first dealer they admitted they never drove the truck. The second dealer called me to pick it up because nothing was wrong and also admitted to not having driven it. After I demanded they drive it, they called back still saying nothing is wrong. "The computer would show it if there was a problem." The third dealer has it now, drove it this morning, guess what? "There's nothing wrong, maybe you can come and show us."
I cannot believe the industry has lost the ability to diagnose vehicles beyond what a computer tells them. Do techs not check compression or ignition or fuel pressure any more? Seems to me a valve issue for example could be the cause of all my symptoms, or fuel delivery, or weak spark, none of which would show up on the freaking computer.

The truck always ran perfect till two days ago. went to start it in the middle of the day , it would barely start, when it did it was missing bad. then seemed to clear up a little after about 30 seconds but still missing. they thought they got some bad fuel. so they dropped the tank cleaned it all out and got new fuel, no change.
Him and a so called mechanic "kid from fire stone" played around switching coil packs around from the injectors with no change. He tells me that the two front cylinders , one on each side are not firing. that those two spark plugs are coming out fuel soaked after running the truck. He thinks it dropped a lifter or push rod popped out of place.
I took my A/E over and came up with codes p0106 - map sensor, and p0135 - 02 sensor. i cleared them and started the truck, shut it back off ran codes again. He also said they pulled the 02 sensor and it still ran the same.

2011 F150 Limited 4wd 6.2 liter. I just bought the truck a few weeks ago with 26,000 miles. Late last week I began hearing a mild grind/rustling noise that appears to come from the driver's front. It's not terribly loud (loud enough to hear), but it's annoying. It happens when I slow down (on and off the brake and below 25-30 mph) as well as let off and begin to speed up. It doesn't last but a second after I let off the brake and speed up though. The kicker is it does not happen all of the time. I drove it home from work last night and it did not do it one time, but driving to work this morning it happened every time I did what I described above. I have taken it to our local tire/suspension shop and they claim they could not reproduce the sound which does not surprise me. They did a full inspection and found nothing.

I have a 2011 F150 FX4 with the traction control. When the tires spin (like taking off on a hill in the rain - that's when i noticed it) and I let off to let everything settle down, I hear a rattling kind of noise coming from the middle dash area, maybe on the engine compartment side of the firewall. It sounds like a rubber ball in a box being jostled around. What this might be?

2012 F-150 5.0 Rough Idle Upon Start up - YouTube
Whenever I first start my 2012 F-150 with the 5.0, it idles rough and if I step on the gas it acts like either an injector is cutting in and out or it's missing. It doesn't really seem like a miss though, more like an injector/fuel issue. What it could be. If I let it sit and idle it won't go away unless I step on the gas and get it > 2500rpm or so.
