It might be that your engine requires an internal cleaning removing the crankcase and washing the whole throttle body. It might even stall and shutt off because of this problems
Masquatch Dad from United States 6 years ago
Was looking at this thread because I had this problem a few years ago-4-5 years. Remove and clean the throttle body. My 2005 F-150 started doing it again last night. It's intermittent at first then more often until you clean the throttle body. Hope this helps!

The 2008 f150 is famous for the cam phasers rattling and timing guides. It's an expensive fix

Climate control randomly loses power

Ford F-150 2014  68000 miles
The Climate control loses power sometimes the lights flicker on and off. It worked 4 days straight and the next day no power. I checked the fuse and it's fine. Any other fuses that may control the power to the climate control. Does the ECM have any control of the climate control module?

Check engine light flickers and the engine loses acceleration

Ford F-150 2012  57000 miles
When the truck goes over 4000 rpm the check engine light flickers for about 20 seconds, and at that point the truck loses acceleration and then it goes back to normal. The error codes I have are P0300, P0302 and P0306. Thanks for your help!

Those error codes are from the cilinders 3 and 6, check the spark plugs and coils

If this is a manual transmission it sounds like your clutch is slipping, check the fluid level under the hood drivers side next to brake booster

Driver Door lock not working SolvedSolved

Ford F-150 2012  128000 miles
The driver's door lock doesn't work, but the passenger-side door lock does. The driver's door will unlock with the remote or the door keypad, but not with the switch, and it won't unlock the other doors. In doing some more testing with the wire hardness, I have now lost power to the front windrows, both the driver's side and the passenger's side

Driver's side door lock doesn't function.
JoeBer from Canada 6 months ago
Yes, it was just the driver's door lock, but the remote would work, and the door panel on the outside worked; just the switch in the door, passenger side, worked.

Fails after starting

Ford F-150 2007  121000 miles
My truck starts normally, but as I'm accelerating it starts failing, the more I accelerate the more it fails, it loses power, the check enging light and a wrench indicator light come on, and while driving uphill it overheats. Please help me!

It could be because of dirty injectors, it might also be the fuel filter that is underneath the driver's seat, check that first to see if it's clogged. If it still fails you should check the fuel pump, it has a filter for the fuel in the tank that goes to the injectors. The stronger the acceleration, the more power it would lose.

Won't turn over not getting fuel

Ford F-150 2012 F-150/3.7/v6 167000 miles
Replaced fuel pump but still get signs. It's a fuel pump. Think it's fuses. Loses power, Dogg's out, acts like transmission out, I have to manually change gears for it to try and go, backfires under hood also during all this. Then after a spell it runs fine. Unless gas is gone. Then it's hard to start have to add are lease half tank bang on it and constantly spray starting fluid with pedale to medal then after three cans starts. Does this Only when a quarter to none of gas in the tank left though. They say catalyst converter are clogged up is why ts doing that.

It sounds like there may be multiple issues with your Ford F-150. Here are a few possibilities:

Fuel pump: If the fuel pump was recently replaced but you're still experiencing problems with your vehicle starting, it's possible that the new fuel pump wasn't installed correctly, or that there's a problem with the wiring or fuel lines that is affecting its performance.
Fuel system: If you're experiencing problems with the fuel system, such as the engine losing power or the vehicle stalling, there could be an issue with the fuel filter, fuel pressure regulator, or injectors.
Catalytic converter: If the catalytic converter is clogged, this can cause issues with the engine's performance, including reduced power and backfires.
Electrical: If you're experiencing problems with the electrical system, such as the starter or fuel pump not engaging, there could be a problem with the fuses, battery, alternator, or wiring.

Multiple random misfire code 0300

Ford F-150 2013  75600 miles
While driving the engine just lost power. When you depress the acclerator it was as you are not getting any fuel. I had it towed to a shop, the shop said they diagnosed the problem and it was the fuel pump, it was not getting the right amout of pressure. They replaced the fuel pump. When I picked up the truck it had a little rattle when changing gears, the mechanic said that the computer may needed to be reset! Drove the vehicle for a day and it shut down again with the same problems. Had to have it towed back to the shop.

I have the same problem. It happens randomly, a lot of times after rain or sitting for days without starting. When it happens, the check engine light comes on and the truck has no acceleration. I turn off the truck and wait a few minutes, then it runs fine. The check engine light disappears after a while most times. It's a very confusing situation. I've changed the coil packs, the plugs and wires. It still does it periodically.

I have had the exact same issue on my 2018 3.5 ecoboost. I read codes, took it to Ford, then took it to another mechanic after Ford couldn't figure it out. Still have the same issue. The second mechanic shop said it was a condensation build up on the drivers side of the intercooler, so they drilled a hole to let it drain, but didn't make a difference. I cannot tow, and cannot accelerate more than say ~80% without sputtering and complete loss of power.

You covered all of what I would suggest. Knowing all of that is good, and you've had dash board issues would point me towards the ignition.

Problems while driving

Ford F-150 2005  250000 miles
The truck has the check engine light on, but when I start it and accelerate it I get a wrench warning light and it starts failing and loses power, and the AC stops working. I had that problem before and using a carburetor cleaning product on the admission fixed it for a long time, but now it happened again and I can't fix it.
