Got My Coils today , look like good quality ,now I plan to put them in sometime during xmas newyears shut down holiday so I may post some question during that period if I run in to any problems. Have a Happy and safe holiday everyone Steve....:santa:

 

Damn , I should order a fresh set since I have the engine in pieces and in the back of the truck - They would prolly be here in about 3 days - perfect!

Plus I have that 25% off coupon

 

Say what??? Did i miss something when i was off to Georgia????

 

No, didn't miss anything Just fixing some little things/ replacing old parts/ cleaning sh^t up. Gottuh a little carried away with it tho -

That's alright, it's fun

Gutted the brake system / replaced EVERYTHING but the pedal, Installed a new exhaust (Cat back), Dropped the tank, cleaned the pump/tank - Working on the motor now.

 

With the help of those here I tackled the job of replacing COPS and spark plugs in the driveway this fall. I've put several thousand miles on the global COPS and all is well.
Along w/ all I learned here...
1) took a couple pictures first for vaccum lines etc just in case, but did not need em.
2)I used a shop-vac and a bicycle pump to clear the recesses before plug removal. Mirror and flash light for inspection
3)Only removed fuel rail on driver side, found the trade off worth while to leave the other one on. Was not a big deal on the pass. side
4) bought the variety pack of extensions and used them all for the back plugs.
5) Took me about 9 hrs start to finish, might make me slow but I didn't break anything, no extra pieces, and saved what I figured to be about $1,100 based on shop quotes.
Good luck to you and thanks to those generous with their time and wisdom
Matt

 

Thanks Matt I start with the pass side then and see how it goes from there.............Steve

 

Ok its 1pm Saturday going to start changing plugs and COPs out look for post if I have any problem will be keeping u updated...let the party begin...Steve

 

Started on the passengers side Took me 4 hours, took my time,back plug was the hardest to break lose,used all the info I got from this site so it went pretty good nothing broke, striped or cross threaded ,did not pull the fuel rail on this side,just took the 2screws out of intake to give me a little movement with the fuel rail. Put everything back together and started it up took about 30 seconds for the motor to smooth out ,took it for a spin have no misses motor running smooth.Driver side tomorrow.These are globals COP to so I am good on 4 for 4 so far , kind of worried about that after seeing other post on this site. Steve

 

Chances are you will be fine with the other 4. I think the % rate is low on failures, I just happened to be in the low % rate.
You will find that cylinders 5, 6 , & 7 are pretty easy, # 8 is a little tricky but you won't have to move the fuel rail on that side either. I found that the drivers side (5,6,7,8) was the easier side to do. You will be happy when it's done. It makes a big improvment all around.

 

Glad to hear that news thought the drivers side might be tougher,yea I hope the other 4 COP 's are good,hate to have to tear one back out again.Seen you been having some problems with global,have you had any luck yet on getting a replacement? Thanks

 

Waiting to see if it works out.
The truck is running great with an aftermarket that was already on the # 3 cylinder(previous owner had a couple on when I bought the truck).
If you have a problem with a COP, you already have 8 used to choose from. Just make sure you inspect the spring connector and the boot real well before you put one of the used ones back on. Keep in mind, you can run to your local NAPA and buy a single boot and spring connector to put on the used COP if you have to, about $7.00 each I think. I had 3 new one's kicking around from NAPA so I put the new connector and boot on until I can get a new COP put on that cylinder. Good luck with the other side. Let us know how it works out for you.
I hope you havn't been shy with the dielectric grease inside the boots on the new COP's.

 

This week I plan on putting on 8 new COP's when they come in along with new Motorcraft plugs on an 01 5.4L with 70,000. I also plan on taking the throttle body off and giving it a good cleaning. Last week I did it all on my 97 Expedition which I just sold and boy did it run good afterwards. I found it is very easy to change plugs with the throttle body off. I also find I save a lot of time by just taking the fuel rails off instead of working around them. The rails are very easy to take off and put back on. Only adds about 5 minutes. It will only take me about 4 hours to do all that while taking my time to make sure I don't screw anything up since Im just a self learner.

 

COP and Plugs change is all done would I do it again? yes, I am pretty sure the 2nd time would go a lot quicker.Spent about 3 hours on the driver side today,ended up having to pull the fuel rail to get to #3 COP screw, just could not get on it with any combination of sockets ,universal ,and extension I had.
The engine is running real smooth now ,no more roughness at idle and hopfully this will take care of the occasional misfires during rainy weather.Thanks to everyone that post the info on this site to do these jobs very helpfull.Did have one question how comes the MC COP's have a solid piece at the end of the spring and globals don't, does it make a differents?
Next Job clean throttle body.Thanks and Happy New Year

Pictures of my Plugs at 59K and 10 years in truck,looked pretty desent yet.

If you used lots of dielectric grease you shouldnt have a problem with missfires.

 

You get carried away quite often.
Hope thing are well for you
