I've read a nunber of post on other sites about the coils burning out on the V10. Some even suggest carrying spares.
What's your take on this topic?
Thanks for the fed back
Jim

Problems with the COP's on the V10 are no more or no less then with any other vehicle. A COP is easily obtained at Auto parts places and are easy to change for most anyone. If you are going to carry a spare COP you might just as well carry a zillion other engine parts that might / could fail.

I would like to know as well. It seems noone else has had a problem. I had a miss and had one changed. I think it cost me over $300.00 I picked the unit up and there was still a miss. They said it was a second coil. Apparently Ford recommends you change all of them at one time. Well at over $100.00 each plus labour that's not going to happen. I heard somewhere driving in really wet conditions causes these things to burn. I have a 2001 Adventurer 35-U. Since the second one being replaced for another $250.00 I haven't had any problems.

I had a coil go bad on my 1999 expedition at about 80,000 miles. It was the strangest thing in that I had been driving over an hour without any problem. I pulled into the drive, shut it off and went into the house. When I came out about 10 minutes later to move the truck it started missing the moment it was started.
I took it to the Ford garage to find out it was a coil. They replaced it and I was on my way. There was no recommendation for changing more than the coil that had gone bad. The truck has another 5,000 miles on it since then with no other problems.
They seem to have a low enough failure rate that wouldn't warrant carrying spare parts. Even if you did it would be difficult to tell which one(s) failed without a scan gauge. You could spend the better part of the day changing out coils hoping you'll find the right one, and that it's the only one.
PS: Our 01 Adventurer has over 60,000 miles without problems.

I realize this is a "little" OT but thought it good to post for info.
Here is one thing to check and it is for both the 4-thread V-10 heads and the 9-thread heads.
Ford doesn't torque the plugs sufficiently. They tend to loosen, then BAM and you've just had your plug shoot out stripping the head and totaling the coil on that cylinder.
Check each plug by removing the coil, then plug and inspect the threads on the plug and in the head. If o.k., replace the plug (now is a good time to either re-gap the old one or replace with a re-gapped new plug) and re-torque to I think 34 ft/# instead of Ford's 17 ft/# and then replace the coil and cap.
Here is a site that has develpoed a repair should the unthinkable happen. The owner is very nice and recommends this proces BEFORE you need his or someone elses services.
http://www.blownoutsparkplug.com/
I talked to him when we were thinking about getting a V-10 coach for info on the issue since I had heard about it from several friends.

If you get what feels like a miss from driving when it's really wet outside it's most likley because your air filter is water soaked. This a well known problem with the Ford V10 motorhomes. There is a fix: Water ingestion

Well I was three days from leaving Kingston to go to Arizona and when I took the RV out for a spin I have another miss. There was nothing wrong the last time I drove it in Sept. It has been sitting in my driveway for three months and now it feels like another coil. It is not all the time and when it starts I can ease up on the gas and then reapply my foot to the gas pedal and it seems to go away for a bit. If it were a coil wouldn't it be constant? Man is this thing allergic to cold? I bought a K&N metal air filter. Would this water ingestion apply to that as well?

If you haven't driven the coach in rainy weather since you installed the new air filter, then water ingestion shouldn't be the problem.

Here's some information on the Ford COP's I picked up from another forum that may be of interest to some:
"Thought I would warn you guys, I had a #5 spark plug wire and "coil" go out. Reason: There is a water hose that goes over the top of this area and mine had a leak in a clamp. The water ran down the spark plug wire onto the coil which shorted it out. Tnis evidently took a long time because the coil had a lot of rust on it. Quite costly when your on the road, to the tune of $281.00. So you might check all plug wires and coils."

If I understand correctly the metal K&N filters are soaked in oil and sometimes if there is too much oil it will corrupt the Mass Air Flow sensor and cause problems such as you are decribing.

I've had the new air filter in for two years now. I do exactly as it says to clean it. I just looked and last year I had the two coils replaced Nov. 27th Dec. 1st. It has to be something to do with the cold weather. It doesn't seem like too many other people have had this problem that have V-10's. I'm going to take the boot off today and see if I see anything. I wondered if I put a light bulb in there and left it on would it dry something out. If I didn't know better I would think it was a dirty gas line filter because of the being able to get rid of the miss. I changed it last year just before I took it in to the garage so it shouldn't be that. Maybe it is this Mass Air Flow sensor that is faulty. Wouldn't they pick that up on a scan if it were that?

It turned out to be two coils again this year to the tune of another 850.00 It was one of the same coils as last year. There has to be something causing these coils to burn out. I'm going to get a hold of Ford and see if they can help me with this problem, either that or I better learn pretty fast how to replace them myself. I finally did get going to Arizona.
I guess no one else is having problems with coils but me.

That is somewhat unusual, hope you can find out what's causing the failures, and if you do, please let us know.

I sure hope you did not pay $850.00 for two COP's and install of same. Do you realize COP's are under $200.00 each and takes about 2 minutes to change out one..
(COP = Coil on Plug)
