does that apply if you have an 2003 Eddie Bauer expedition with a 5.4L engine instead of a 4.6?

Yes, it applied to my 2003 XLT with the 5.4 engine.
#66 of 113 New coils fixed problems with our 2003
Jan 10, 2010 (7:47 pm)
This thread was invaluable in helping diagnose/fix the problems we were having with out 2003 5.4L. Last year it started misfiring after a rain so got a code reader at Harbor Freight on sale for about $45. After a few weeks I got a P0308 code (no codes initially). I ordered a set of coils off ebay and replaced #8 plug/coil. Problem solved. This year during our first decent rain (SoCal) the misfiring returned. Got codes P0306, P0307. Replaced all the coils/plugs (111k), 6 & 7 first and problem solved again. Then the misfire came back. It slowly got worse until I finally got a P0308 code. Checked the one year old #8 coil and the wire coil in the rubber boot was all rusty. Replaced the #8 coil again, problem solved. Looking back all the coils on the left bank had moisture in the boots and rust. All the right ones were bone dry. I got a hose and ran some water on the windshield and a steady stream was dripping onto the left valve cover and splashing onto the #6, 7 & 8 coils. The heat shield blanket was installed under the plastic trim at the base of the windshield. My brother's F-150 has the blanket installed neatly below the plastic trim. I trimmed the blanket and siliconed under the plastic trim to stop the leak. This will, hopefully, help keep the coils drier.

Thanks for the feedback babichrt, glad to have been a part of helping someone else. Also, thanks for the tip on the hear shield blanket, I'll need to take a look at this. One tip I have is that I have started using a silicon grease between the plug & boots to seal water out. Just a little around the widest part of the porcelan base of the plug so that it doesn't impact the electrical connection. Has worked great on my dirtbike in recent mud races.

First of all..I'm a girl - I had the same problem this weekend. It rained really hard and I had the sputtering the next day (a Saturday). To make a long story short, it was the #3 ignition coil. I took it to a mechanic and got it fixed and I got all the the spark plugs changed too. It cost 627.00 with parts being 125.00 for the coil and 12.00 each for the spark plugs and 95/hr for 3 hours of labor. They tried to talk me into getting all the coils replaced but I said no. I think I was ripped off. Was I?

You did alright. $95.00 hr for a mechanic is a fair rate. $125.00 for the coil was high but it was probably one from the local dealer so it was high to begin with. $12 for a plug is reasonable (one for my motorcycle runs $30.00). However, the #'s above add up to $506.00. Either there's an extremely high sales tax where you live or ...... I'm curious, did you read this forum before or after you had it repaired?

The plug job in my area runs around $400 with plugs (unless they start snapping off, which they are prone to do). Coils from the dealer are very expensive, you can go on ebay and buy the set of 8 for less than $100. So maybe you got taken a bit, but in the end you are up and running and you won't make that mistake again. I'd say invest in the whole set of coils and changethe rest of them yourself.
#72 of 113 2000 Expedition stalls in cold weather and sluggish in hot weather
Aug 29, 2010 (8:39 pm)
2000 Expedition, 185,000 mi. Runs great most of the time but the "check engine soon" light came last year. Had it checked and the read was "lean left" or "lean right". My mechanic turned it off and it did not come on again until the outside air temp dropped below (approx.) 30 degrees. Throughout the spring, when the temp dropped, the engine would begin to idle rough and occassionally stall when I came to a stop no matter how warm up the engine was. Now when the outside air temp gets above 90, the engine acts very sluggish and low on power. Initially the mechanics I spoke with thought "check engine soon" light reading indicated a manifold gasket problem but we decided not to do anything because the car runs great 98% of the time. I'm beginning to think this is more likely to be a fuel pump issue than a gasket problem. Your thoughts will be appreciated.
