I'm very well aware of the warranty law. If Ford (their authorized agent - i.e. the dealer) determines that the use of a part that does not meet factory specs has caused a failure, they ARE allowed to refuse warranty coverage. They cannot void the coverage if you use a non-Motorcraft air filter, as long as the replacement meets Ford specs. However, an aftermarket intake does not meet Ford specs, and PCM modifications don't either. It's a judgment call, and your particular dealer is just being a jerk about it. There is also no law against a dealer to refuse to work on your vehicle, they are an independent business, not owned by Ford Motor Company. Your only redress is go up through the chain at Ford, where you may or may not meet with any success.

 

I will be curious to see what the solution was. In the Mustang world the same problem has routinely been complained about. However, the cause had nothing to do with the transmission. In older cars the gas pedal is attached to the EFI or the carb via a mechanical cable. In newer cars they are "drive by wire" and use an electronic connection between the pedal and a sensor. Essentially when you press the gas pedal it moves a set of small pieces of metal across another metal sensor which sends a signal to the engine/EFI. That is probably not a great way to explain it but you get the idea. With the drive by wire system they are notoriously slow in translating pedal movement to acceleration.

Some Mustang owners actually opened up the sensor module and modified the brushes by bending them slightly to make better contact with the receiver. This is risky and a better solution was usually found in an aftermarket tune. My Mustang suffered the same lag but after putting a Tillman Speed tune on my car the lag was almost entirely gone. I would assume that our newer F150's use the same drive by wire technology. However, I haven't noticed nearly the lag with my 07 screw as my 07 Mustang.

 

Straight out of Ford's Warranty Guide:

Damage Caused by Alteration or Modification
The New Vehicle Limited Warranty does not cover any damage caused by:
• alterations or modifications of the vehicle, including the body, chassis, or components, after the vehicle leaves the control of Ford Motor Company
• tampering with the vehicle, tampering with the emissions systems or with the other parts that affect these systems (for example, but not limited to exhaust and intake systems)
• the installation or use of a non-Ford Motor Company part (other than a certified emissions part) or any part (Ford or non-Ford) designed for off-road use only installed after the vehicle leaves the control of Ford Motor Company, if the installed part fails or causes a Ford part to fail. Examples include, but are not limited to lift kits, oversized tires, roll bars, cellular phones, alarm systems, automatic starting systems and performance-enhancing powertrain components or software and performance ‘‘chips’’. [Emphasis added]

All Magnuson-Moss does is prevent Ford from denying coverage for a repair that was not caused by the aftermarket component. In other words, Ford couldn't deny coverage for your front wheels falling off, if they see that intake. On the other hand, if you had an engine failure, and Ford denies coverage because of that intake, the burden of proof will be on you to prove that the aftermarket component was NOT responsible for the failure. You're pretty much out-lawyered at that point and would have to hire experts to prove that the component did not cause the engine failure.

 

Yeah no problem, if something I did destroys my truck I would never expect them to cover it... I have read the the thing.

 

So, what fixed it?

 

Looks like he got a custom dyno tune.

 

Yes, a trip to the dyno.


Were you guys all aware that Ford won't even allow you more than like 28% of your available throttle off idle? You can't even get to WOT until 4500rpm. Betcha you werent aware of that.

 

The dyno will give you the read but what did they change? Did you go with an aftermarket tune that fixed the throttle lag? In other words, re-programming the PCM as I had to do with my Mustang?

 

Sounds alot to me like somebody who knowingly bought a 5,000+ lb. full size pickup truck then whines and complains because it doesn't perform like a Ferrari.
Kids !!

 

Apparently you have trouble reading. When you step on the gas pedal of your truck, does it take 3, 4 sometimes 5 seconds before it starts to accelerate?

I have 2 friends at work that also have 2010 with 5.4 and neither of their trucks have the same issue. Yes its a truck. No I am not racing anyone and could care less how "fast" it is.

 

My 2005 had a similar hesitation and when I took it to the dealer and told them it was going to get me killed when trying to pass on two lanes, they quickly did a reflash which helped it but it was still a dog. A tune fixed that about 100,000 miles ago. I have never raced it so there are those of us that just want a truck to perform to it's potentil when called upon and we have no intention of racing.

 

Thank you!

 

Mine does the exact same thing. The dealer says it is a software issue that Ford is working on. They re flashed the computer to no avail. I agree, this is a dangerous situation when manuevering in traffic.

 

I have a delay in my tranny as well. 2010 6spd. But mine makes a loud clicking sound at takeoff as well.

 

No it doesn't.
I also don't recall in my post where I said Anything about you "racing anyone"
