Ford F-150 (2009-2014) :: 2012 - Knock And Power Lag During Acceleration
Dec 16, 2016
My 2012 3.5 ecoboost has a knock and power lag during acceleration. Dealer diagnosed as timing chain and cam shaft phasers. I asked if this was common and they said, "yes, it will happen to all of them at some point." Basically, he said if you baby the truck it will take longer, but still happen. Wasn't surprised I'm having it at 67k miles as he saw another recently at 70k. The power drop is dramatic, so I don't see any option, but to have the work done.

I have a 2012 4x4 EB CC. In 6th gear, on the highway between 1200-1700 RPM's, during a slow acceleration, it feels like it is missing or shuddering. It is most pronounced going up a hill, and/or towing something. As soon as you get above about 1700, it goes away. Rig needs to be fully warmed up (not just the engine, but tranny/drivetrain). Needless to say, this is generally from about 52-65 mph, which is most highway (not freeway) driving I do. At times it's so bad my wife says it's time to get a Chebby.
Had it in about a year ago, couldn't duplicate it. Took it in this last week. Did the TSB on the plugs, and was told that would fix it. It didn't. Took it back in; they couldn't duplicate the issue. Rotated the tires hoping that might do something. Took the head service guy for a ride, and made it happen; it was very obvious then. It seems like the tachometer should bounce or shudder a bit when it's doing it, but nothing. It's going back in on Monday to see what they can do.

Installed power fold in mirrors on a 2012 FX4? My truck does have power mirrors but not the fold in option.

On a 2012 F-150, does the motor need to be running to use the AC outlet?

Recently, my CEL came on. I had the guys at Autozone read the code and they said it was the knock sensor on bank 2. I disconnected the battery to clear it but after 100 miles or so it came back on. Idling, my engine runs as quietly as it ever has (can't tell it's running if the windows are up) so I'm hoping that the sensor has gone bad. I can't hear any knock at any speed but the re-appearance of the light has noticeably affected the engine performance. Any link that even shows where the sensor is located? If I can find it, I can replace it.

My 2011 F-150 Super crew eb has started to have a knock that comes from under the dash in the radio area. It doesn't occur every time it's started. It is 3 or 4 knocks that sound like a plastic gear slipping, then it stops. I am thinking something in the vent/defrost door. Is it vacuum operated or electronic? Any thoughts?

I took delivery of my 2012 FX4 Eco in January and about a month or so later I began experiencing a loss of power and the check engine light would come on then go off again. This happened the first time in Houston traffic one day so I was pretty concerned needless to say but then it cleared itself shortly thereafter. However, heading back home it occurred again on the highway while I was trying to pass and she just didn't have the power. I took it to a Houston dealer late in the afternoon before I left but no codes were found and when I got it back to my local dealer it was determined the left side catalytic converter was bad and it was subsequently replaced. Well, it happened again and it's back in the shop while I am offshore so they have plenty of time to take care of it.

I have an issue with my new 2011 F150 FX4 super crew with 5.0. I put a Rough Country level kit on the front struts which raised it 2.5 inches and looks great. The issue is that there is a low speed knock heard on the left side and felt through to the steering wheel. The truck has been aligned to factory specs. all bolts have been tightened, the strut has been taken off to check the top mounting bolts. Nothing appears to loose. Can't find anything. Am I forgetting something. Rough Country said it can't be the kit. It has bee used for sometime with no issues.

I now have 500 Miles on my LE. Driven soft Never over 2,500 rpm except, one time I accelerated to 4,500 RPM in first. Short 5 Mile trips.
Engine knock on start-up (Lasts one second)
sounds like a lifter pumping up.
Only happens occasionally.
Happened last night after driving 40 Miles and parking it for two hours.
Is this normal? I have noticed this since the first 10 Miles on the odometer. Figured it was the 0W-20 Oil.
My friend has a 2003 Echo with 100,000 miles and it does not do this.

Every once in a while, I'll feel a vibration in the gas pedal. It happens under acceleration, and typically if I'm pushing down and it has not downshifted yet. Then once it downshifts the vibration is less noticeable.
I know there have been issues with the Electronic Throttle Control on these drive-by-wire trucks, particularly on the Super Duty trucks.

I have a 2010 Ford F150 Lariat with 111000 miles on it and now I have a ticking noise under acceleration only and after reading some stuff on here that makes me believe that it is the cam phasers. The question I have is what kind of damage can this cause? Is this something that I can continue running with and does the noise get worse and if so how much worse?

2014 ecoboost Supercrew 4x4 20k miles
It happened at the most inopportune time. I was in the left lane of a two lane road passing a slow truck on a somewhat busy road and it happened. Shudder, loss of power, check engine light on, limp mode. I was next to the cab of the truck when it happened and had to slow and get behind him to pull over and shut it down.
Potentially a dangerous situation.
I rarely step on it, but when I do, I expect it to work.
I baby this truck, almost 18 mpg lifetime average for the 20k miles on this truck.
I took it directly to the dealer to get checked out.
Codes P0305 and P0306.
Checked for carbon tracking on plugs, none found.
Performed a power balance and coil stress test, no problem found.
Removed CAC deflector for inspection, no issues found.
Updated PCM to latest calibration.

I have about 22,000 miles on the odometer. I bought it as a CPO with 2200 miles on it. Truck is all stock.
I have heard this noise only once before. I will accelerate up to about 45mph, back off to about 30-35 possibly less, then accelerate again. When I do, it downshifts and I hear a lout noise that sounds like a yelp a dog would make if startled.

I have a 2011 SCREW (build date late April) where the turbos started cycling on and off during acceleration or under load when pulling a trailer or going into a strong head wind. It started at about 18,000 miles and I brought it in to the dealer. They road tested it and could not duplicate. It continued doing it and I had a dealer tech ride with me at the next oil change. He confirmed the problem...this was around 22,000 miles.
Dealership contacted Ford and although they were aware of it (something to do with opening and closing of waste gates if that makes sense) they did not have a fix. They said to check back after the holidays. Since then it has gotten worse cycling on and off under a lesser load. The dealership checked again two days ago with Ford and still no solution but they thought the eventual fix would be to re-flash the computer.

15k on my Platinum, love the truck. I've had a handful of chimes and flashes of something on the productivity screen, most recent on an acceleration, pretty good, no WOT, but 2/3 or so, hear the chime and see the orange box on the screen, but it is gone before I can see any text etc.
Oil level good, 10% til next change. possible tire sensor? Never had a TPMS prompt. Have noticed it has only been when the outside temp is around 30 degrees F, or lower.

Start from the beginning 2011 screw 4X4 ecoboost 46,000 miles, under wide open throttle and over 3,500 rpm I'm getting a misfire, diagnosis "I usually chicken out when I hit 80+ in 3rd". Misfire occurs in 1st, 2nd, and 3rd don't have enough road to try a higher speed or gear.

I have an 09 F150 4x4 with 116,000 miles on the clock. I am having an issue with moderate acceleration and felt mostly in 3rd gear. I changed the spark plugs at 106,000 miles with OEM replacements. I have had this issue since about 80,000 miles but intermittently. It seems its starting to get worse as time goes by. The problem is both cold or warm and doesn't happen all the time but now about 80%. Light acceleration is good and full acceleration is great with no issues.
Feels more like running out of fuel but not to the point of stumbling. Possible misfire that is not being detected. No check engine light lit. Tranny shifts perfect. Idles extremely smooth. I was thinking a coil problem but with no engine light, I don't want to try to guess which one. So far, this truck has been awesome and has needed nothing but tires and routine maintenance. I pull trailers consistently and this beast is not abused nor babied.

I picked up a 2014 F150 with the EcoBoost engine a couple weeks back and while so far I love it, I can't get over how quiet it is. So, to my question, has anyone done anything with the exhaust to get some of that truck sound back. A slight rumble on acceleration would be nice to have and maybe get some gains out of it, but thats minimal.

Was driving to Airport yesterday and out of nowhere got the flashing check engine and shudder/limp mode while trying to merge/accelerate onto the onramp (had to gun it to go around someone who decided to stop on the onramp for no reason). Let off the gas and the blinking went away. Upon leaving the airport I was accelerating again at highway speed to pass and got the blinking light and then a solid CEL. Found my way to a Autozone and got the code read. P0301 Cylinder#1 Misfire. Was suggested to change COP and plug.
Changed COP on the spot and had to drive it home to my tools to install plug. Thought maybe that since the CEL was still on solid after changing that the code needed to be cleared for the PCM to function normally again. Still have shudder when accelerating hard, so thought it might have been injectors so got cleaning service done at Goodyear. Still have the issue. Disconnected battery and performed IDLE relearn just now and it still is shuddering upon hard acceleration. Stumbled across TSB 12-6-4 which speaks to my symptoms.......I do not have the plate which in turn would imply I do not have the PCM update it references.
I have not noticed a misfire nor had an acceleration issue before so this was a surprise to come out of nowhere. I'm going to be calling my dealership in the morning.

I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.

Have a ecoboost that moans and groans under light acceleration ? I asked the dealer about it and he said everything was fine. I guess its the turbo blow off valve. It run fine, just weird noises under the hood.
