2002 Ford F-150: check engine light

Filed Jun 17, 2022 · Engine · GA

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.

SUA sudden unwanted acceleration, at least 4 times. No floor mats. 1st time truck surged back and forth a little then accelerated full throttle. I went to neutral. I kicked gas pedal although gas peddle was not depressed. It stopped. I was shook up but in control. I decided to remove throttle body and clean extensively. Replaced TB Sensor w/ genuine Ford part and replaced throttle valve on top. Hoped for the best. Still have the problem. 2002 F 150 XL 4.2 purchased new. I still have truck because its been such a great truck, I never felt like it was time to move on. It runs like new and I've taken care of it. I am writing this info for safety and only safety. I've been researching this issue. trying to solve problem. I took truck to qualified shop where mechanic is known to me and he was a little stumped. No codes, no check engine light. Can't solve the puzzle? So, I'm on top of the possibility of it happening. I really don't go anywhere w/ truck, to the store and back pretty much. So when its happens, I'm fast to go to neutral. I also feel like if I wanted to show somebody what I'm talking about, all they have to do is get in. I'm almost positive if I punch the gas peddle just a little, say to pass a slow driver, it'll go like hell. I have started thinking about my next truck. But no way I'm trading or selling this truck and passing the problem to someone else. So, I'm dealing with it and really hope my experience helps. I've read the story's on line. Because I've lived it, I can tell you its a bit terrifying. That's my story Thank You Jim Winn

About 6months ago, cruising about 60mph; heard a "pop", lost engine power, engine light on,...pulled over and discovered #3 cylinder missing the spark plug and the cop broken. Had it towed home (approx 25miles); went online and discovered it's a systemic problem with many other ford v8-v10 1997-2003 motors.

Dt: contact states her vehicle is stalling while driving at any speed. The only thing that signals that the vehicle is stalling is that the vehicle will jerk and rpms drop. This happens with the vehicle stalling everyday. The service dealer can not determine what is wrong with the vehicle because the service engine light is not illuminated. The contact is taking the vehicle to the service dealer today.
