Any possible way to turn a stupid COP setup into good ol school wire's? I absolutely am at my wit's end and am entirely fed up with ford's craptacular wonderously pathetic design! I have never had so much issue with a vehicle in my life as I have with these retarded Modular motors with COP setups. I owned a GM for christ sakes with no dilemma's or issues remotely close in comparison of pure aggrevation.

LOL ok but seriously anyone ever consider it?

 

I totally understand your frustration, but there is hope.
The COP setup isn't as bad as you might think. There are literally a million trucks on the road with this set up. Not sure what issues or codes you are getting so definitely post those. Many people are astounded at the price of OEM Motorcraft COPs. Do yourself a favor, go to Global Automotive on E-bay and order a set for $100. You can get a set of Motorcraft Spark plugs for $25.
Post back with the following:
Year
Model
Engine Size
Trouble Codes
Issues you are experiencing

When replacing the COPs or simply inspecting the plugs it is always best to clean them and use di-electric grease on the boot before re-seating the COPs.

 

2000 F150 5.4L
P0171, P0174
Truck runs almost as if it has a miss, under any type of load it shakes.
(example: put in R or D doesn't matter which, hold the brake and pull throttle to about 1200rpm it shakes, like something is off center. At idle you hear a small lope in the idle and occassionally the idle kicks right out and bogs... Driving around if I put the throttle down it's like i have a 2hp lawn mower motor under the hood.)
I have been told vacuum leaks (wrong, none found all lines were removed and checked and double/triple checked...), PCV system(replaced pcv valve and no leaks), cleaned the stupid little MAF sensor even tho it appeared clean, has new plugs in it and have replaced a one of the COP's as it fell apart when I did plugs lol. Has a fairly new (5month old) fuel filter in it.

About ready to drop a match in a pail of gasoline on this thing...any and all advice/help greatly appreciated.

 

Replace all of your COP's to get it running right. The good Ford Techs on here, will tell you when one goes the rest are sure to follow.
Ebay sells them thru Uneeksupply for $85.00, including shipping.
You want to get rid of the COP's, pull the 5.4L and put in a 4.6L.
That is your only option and you will be running on 2 coil-paks with wires.
IMO that is rediculous. I pulled my COP's a year ago and 6 were original OEM with 137,000 miles.
One other option is,... go back to GM.

 

You are experiencing a "lean" misfire.The codes you referred to, P0171, P0174ARE lean codes. The computer is adding fuel to a point where it sees there is a problem. That means there is excess air entering the engine past the MAF. If you have a lot of miles, it could be a bad intake manifold gasket. You definitely have a vacuum leak with those codes. Try spraying carb cleaner anywhere that possibly could cause an air leak. If you have a cheap PCV valve, I have seen those cause problems. A bad MAF will cause these problems, too. Might want to spend the diag fee at a dealer you trust to come up with your solution. I've seen people spend $300-400 on parts and not fix a $2 problem.

 

Thats damn near swearing lol tested 5 of the 8 COP's (will do rest when i get a chance...), all measured at 1ohm... is that right as the Haynes book says it should be .55ohm....

 

Just nevermind me.

 

i know people that swap from a 4.6L to a 5.4L can keep there coil packs and wire set up rather than switching to a COP set up and all those harnesses... but you have the 5.4 so hummm......

 

I know you checked the vacuum system, but did you take a look at the elbow that goes into the drivers side valve cover? I replaced my IAC today, cleaned the MAF and replaced the PCV, while I was at it I took a look at my vacuum lines. The elbow going into the drivers side valve cover was rotted on the inside of the curve. I'm replacing all 3 rubber elbows that I found, O'Reilly and Advance didn't have any of them, hopefully I'll have better luck at NAPA tomorrow.

Wish I would have seen Bigbroncs post earlier....

 

.55 ohms is correct on the primary side but you need to check your secondary resistance as well. Your secondary resistance should be 5.5K ohms
(= 5500 ohms). I have yet to see a new COP acually read 5.5K ohms.
I usually get a reading between 5100 & 5290 ohms on my new COP's
The coil inside the COP (like all elec. coils) break down over time.

Also, FYI....
It is always a good thing to listen to some of the trusted members on this site. My example for this thread is BigBronc. He is a big asset to this forum. There are quite a few ppl on here who offer very good and technical help.
To keep them here, it's always a good thing to acknowledge their help.
Re-read his post and make sure you have completed his recommendations. Someone else suggested the PCV assembly. I replaced the entire assembly for $28.00 from Ford, my 0171/0174 codes went away. That was the last thing I had to do to get rid of a few DTC's.

 

By the way are you checking the COP removed from the engine I hope.
You have to bench test those when you are OHM'ing them.

PS: Pretty much, always trust what your Haynes manual is telling you. I have never (so-far) been given bad info from my manuals.

Hey Brew, is OHM'ing a new word I invented again....

 

Your looking for a low grade misfire. Guess what - it ain't happening unless you throw a CEL. The only way that's gonna happen is if you give her freakin hell right before she starts b^tchen. Don't let up, keep puttin it to her until you gain her respect. IF that happens...- She'll wink at yuh a few times. - Then get yourself up to Auto Zone for the booby prize.

Think they call that the stress test or something ?

 

I think it's a Bootist word or at-least Trible. ? I've heard it before at college - it would echo down the hallway at times. Chick sittin next to me said they had some type of meditation class down the hall.

I checked it out after class, I walked down to the end of the hall, - There wasn't No class rooms down there

Just a crapper

 

where abouts are you from in canada?

 

advice taken, had no power at home today...

but the PCV is a FORD replacement, am aware the codes are for lean, have gone through the vac lines and all appear to not have leaks and when sprayed no surging. The rubber lines are intact and not cracked or wore. The maf may be the source... it's attaching screws aren't attached real well i noticed... it's been siliconed onto the duct piece lol... loss for words... it's sealed up and solid, just the barbed nuts are removable with the sensor :S.

Going to try to get a intake from the wrecker tomorrow and maybe fix my dilemma lol.
