I keep hearing people about the coils going out. Have to say as a former ford senior master tech its not the coil nors fords fault. Its the truck owner for over extending the service on the spark plugs. They only last to about 60k. The gap on the plugs get so large Iit over works the coil when the plugs are slap worn out.
Dont wait for the miss fire or prolong the tune up. Once you change the plugs you will have much better fuel mileage and power. I have 120k on my 06 screw and on my second set of plugs. I do tow with my truck and towing does ware the plugs down pretty fast. If you dont tow at all or go mudding then they should last to about 80k. And put back what came out. Those one piece champion plugs are not worth 2 cents. I use the motorcraft plugs and never seize them. Have never had a problem with them. I have replaced so many coils on my customers cars and trucks cause they thought they knew better and thought they were saving money not doing the plugs. Now they are spending for a tune up plus coils. Now who is saving money now? I have to say if you take care of these motors and trans they will last. My past expedition with a 5.4 had 389k on it. And it never burned oil nor ever had to change one coil. I did my maintenance to the t..
Till to date it now has 415k on the ticker still one hell of a strong engine!
Till today that ex

 

Stick around, - if you want to learn.

 

You sure you have the right site ? You really don't need to lecture the basics around here, seriously. Put the pedestal back in the closet and try helping one and one. You'll learn a little quicker. Can't get away with much BS around these parts. Your welcome to try. Hell, that's no fun.

Good Luck

 

Brew, maybe YOU can learn some stuff from this guy. He's a former Ford master tech and what he says makes complete sense to me.

Nothing wrong with lecturing the basics.

 

Yea right! He sounds like a service manager. If he gives you tickle , eat it up. Grab a seat. You see his other post. That make sense to you as well lol.

Yea , grab a chair.

 

Nope not a service mgr had a few removed when I was with ford though. Since I was one of the few in the us with a ford specialist certification. There are only a few nation wide. That means I can do any repairs or overhauls. Diesel, gas, transmissions, etc. Ford specialist is the highest certification you can get company wide. For the ones that think more about fords I have one question for them and if they could answer this question then my hat goes off to them. What is multiplexing in fords diag terms? Good luck !

 

And a little background I use to race during the dark ages when johnny lighting was first getting into the mnra and fun ford. And have raced against Susan roush and stormin norman. Those are the days where racers had respect and helped one another. Ultimately had a good relationship between one another. Same goes here. Im not benefiting from anything here just trying to help people out. If people in general have better maintenance practices then alot of problems wouldnt be happening. And overall you can enjoy your ride overall.
Now if all people want to do is bash and bash others then other people start buying other makes and models. Whats the fun of having a fourm if people say im not a ford guy anymore cause my truck is a piece of cprap. Cause they didnt know that these new trucks require more maintenance than old push rod motors. Its not cool at all to hear people say that ford builds crap! When it was mostly their fault it turned to crap.

 

In simple terms:

In a vehicle network using time division, it is also referred to as mutliplexing - a way to transfer data between multiple distributed modules using serial data transmission.

And it is nothing new or proprietary to Fords.

Any IT network engineer is familiar with this term.

Now - I have one for you: what is CSMA/CD?

Good luck

That said, it is also well-known that plug gap growth causes a rise in demand for ignition energy and a rise in voltage. However, in free-air, the plug may require, for example, 15k-30k volts to fire with a nominal spec'd gap. Whereas in a combustion chamber it is typically far less due to the fuel/air mixture within. And - Ford COPS have a >60Kv design threshold.

Agree with the 60K plug interval - it IS what Ford now recommends anyway.

BTW - I've been using Champ 7989's for a while now - Zero issues. There are specific steps involved in ensuring these work properly I will admit, that some may not be aware of.

I'm as over-edumacated and **** a detail freak as you will likely ever meet , and a data-hound. And a geek. And love beer. Take that whichever way you wish.

 

You obviously have never owned a push-rod engine or you wouldnt say these engine need more maintenance. I have. lots of them. Points plugs need to be redone way more frequently. Then there's the carburetor god help you if you live in an emissions state. As far as maintenace goes I'll take just about any new car over an old one.

 

Then get your facts straight. All that schooling, background and all you have is a keen (that's even a little weak) grasp of the obvious.

NOBODY with this kind of experience would EVER say the crankcases and transmissions are NOT sealed systems. Just that lack of knowledge right there proves your lack of credibility IMO. You shouldn't be preaching, you SHOULD be asking questions in order to completely understand the combustion engine. It's called misleading and that doesn't help anyone out.

In bold - Who says Ford builds crap around here ? - Or anywhere for that matter. Every once in while you get one , but it's always do to what They're lacking and not the vehicle. You touched on that yes, but bad mouthing Ford products is far less popular then your attempting to make it out to be. Ford is #1 Buddy, - get use to it.

 

BTW- Thanks for those other points made fella's. Well most of yuh anyway.

 

Specify. The hound wants to know!

Wow... I honestly haven't even thought about that acronym since learning the OSI model. The only collision detection for me these days is when my winch hits the handicap parking signs.
