Spark plug replacement

Thanks for this post helped me a bunch. I love this site.

I've had a plug coil replaced in the past ($175-$190 or so) and now have another cylinder misfire code. This time for #5 - apparently the front right, as I'm facing the engine. I'd love to tackle this myself, given the price of parts vs. Taking it to a shop.
The only think I can't seem to find good info on is the fuel rail that runs across the top of the plugs/coils.
I can tell that I'll have to move a bracket/brace on that side, to get down there, but what about the rail? Does that have to come off, too, in order to work on the c.O.P?
Thanks for any help.

I'm happy to report back that I bought the part locally for $40 plus another $1 for the di-electric grease and knocked it out last night. Truck now runs smooth as silk again. What a feeling to have it fixed - and know that I saved around $150 vs. Getting it done at a repair shop, and who knows how much more vs. Taking it to the dealer.

I did go ahead and take off the plastic air intake cover (3 bolts - the plastic piece that says "4.6l Triton" on it.). Also moved the bracket that holds the power steering fluid reservoir. Just made it easier to get my hands in there. Couldn't be more pleased with how it went, and I will not hesitate to take the rest of them on some time soon.

Didn't want to wait for an eBay order to ship, as this chugging/missing had been going on already for a couple of weeks. But, I am going to order a set ($80 (or less!) On eBay) and either have them on hand for the next time one goes out, or just dive in and do 'em all + the plugs sometime soon. My local Ford dlrshp parts dept. Wanted $97! For one coil. (Bought my single at O'Reilly's for $39.99)

Thanks again, Billymac, for the encouragement.

I am replacing the coil over for cylinder 1 and all the spark plugs. I need to know which of the cylinders is cylinder 1 so I can get it replaced. Thanks so much!

I have a 2002 ford f-150, V8 5.4 liter engine, with about 118,000 miles on it. I've kept the vehicle in very good condition since the day I bought it new. But lately i've been experiencing a violent jerking of the truck when I stay in the range of about 40-50 mph, at about 2500-3500 rpm. I've had it in the shop with the suspicion it might be a transmission problem, had the torque converter replaced, changed the spark plugs, etc. But nothing has solved it. If you could help me out, it'd be greatly appreciated.

Thanks,
Alex

I changed the spark plugs on my truck and everything is running right but my service engine light is on. Is this normal when you replace things like spark plugs and is there a way to reset it?

Ii REPLACED COIL PACK AND SPARK PLUG 6 months ago on Cylander 3. Changed the rest to do a tune up and not the #3. Seemed to be fine on test drive then heard a loud bang or pop and the #3 coil pack blew off. The threads on the spark plug seem to be fine no damage. Coil pack damaged. What could have caused this and can I put a new spark plug and coil pack back on without further damage

I need to change the spark plugs on my truck but can not find them. WHere are they located at? V8 4.L

Last week filled up and thought I got a tank of bad gas. Tried dry gas and fuel injector cleaner as a fix. Refiled next week with tank of premium. Still sounds like it has spark plug knock. Today changed the plugs and plug wires and as you give it gas it still has a chattered knock like bad gas or bad plugs or wires. Havent had the money for diagnostic at local ford dealer. What else could it be?Pcv-o2 censors-fuel filter? HELP its kiling my gas millage. This truck has been one of the best trucks Ive ever owned and Im going to drive it til the wheels fall off its spotless in mint condition-just lots of highway millage.
Thanks for any help.

Engine Mechanical problem
2001 Ford F150 6 cyl Two Wheel Drive Automatic

My 2001 F150 has 80K. Starts and runs ok. Fuel economy is 15-16 mpg city .. 18-19 mpg highway.
Last fall mpg started dropping 12mpg city and 15 mpg highway. I've heard from ford mechanics and serviceman that the plugs are good for 100k
Here the truck is at 80k. Would I get better fuel economy and performance if I go ahead and change the plugs? Thanks. George
