1. Coils on top of spark plug get moisture in them when there is just the right kind of rain storm. This makes the coil or coils fail until the dry out. This seems to make the coil eventually go bad. Yes, it is available for inspection. 2. Not sure if its a combination of heat and moisture but sometime right away and sometimes a few minutes into driving the coil or coils fail and the engine loses power. Then if seems to be a random, unpredictable occurrence until it dries out, Very Unsafe. If one coil fails it loses just a little power, but if more than one fails it loses a lot of power and stalls at times. This is why I am writing it up. A few time now, I have gone to pull into traffic and then I lose power and either have to run off the road or just upset the car behind me if they are not too close. 3 & 4. I have advise all the Ford dealerships in my area trying to find one that has a fix yet. The only fix Ford has, is a new designed coil, which does not appear to be any better. The dealership just replaces the coil. I have had all my coils replaced, some 2 or 3 times. 5. It depends, sometime the engine light will come on and advise which coil is misfiring and sometimes if does not. Right now my engine light is on and it displays the #6 coil misfire. Then the engine light will go out after it dries out and stops failing or it will stay off if the coil had gone bad again. I am sure its not just the F 150, but the 4.6 liter engine that is in other vehicles. I started keeping track in 2012. I wrote a letter to Ford in 2015 and they replied, there was no recall. I have several repair receipts and the letter from Ford if you need that. Just search on your site and you will see many complaints. One example Manufacturer Communication number: 041601. If you google "ford fix for moisture in coils" you will see many forums trying to figure out a fix and just complaining.

This is follow up assessment to my 9/22/2019 claim [xxx]- where I found myself in a very dangerous vehicle run away situation that resulted in a rear end accident with another vehicle. My mechanic's first observation when turn ignition key, the engine raced at full throttle out of control. After quickly shutting down engine the symptoms lead my mechanic to test the idle air control valve. Having never seen this dangerous symptom from a bad iacv, he continued to do further test on the iacv only to determine the part was indeed defective. After diagnosing the problem, the defective iacv part was quickly replaced. The engine is now running good again.

#3spark plug blew out of right cylinder head. Since the injector was still pumping fuel into the open chamber this could have caused an engine fire inow have found this to be somewhat of a problem with the 4.6 litre engine due to the aluminum heads.

- Danielson, CT, USA

The spark plug on the passenger side of my vehicle exploded out of the head as soon as I started the vehicle breaking the coil pack in the process. I purchased the vehicle used a year ago and since the plug blew out on me I discovered that this is not the first time this has happened to my truck so it is an ongoing problem.

- Midlothian, VA, USA

While pulling up to a stop light my truck started popping and shaking. I pulled over and opened the hood to find out a spark plug had blown out of the motor. It exploded with such force it broke the coil over housing on the head. I have called Ford and they say they don't know of any issues of this. It is all over the internet about it. They are in court right now over the 2005 and up vehicles having the same issue. I am the original owner and have never had to replace the plugs so they are straight from the factory, and the truck has only 123,000 miles on it. It is now going to cost me over $400 to fix this one plug with no guarantee it won't happen to any other plugs. I'm retired on social security and cannot afford a new truck payment, or continue to fix their defects.
