Ford F-150 (2004-2008) :: Coil Going Bad / Breaking Down?
Dec 31, 2011
I hate it when this happens, but I have a coil breaking down, and I've been advised multiple times to not replace all 8 coils. So how do I figure out which one it is? I am almost sure its a coil, as the plugs do not have enough miles on them to be bad already, and the truck has plenty of power it just has a slight shudder under a load, and the engine light will occasionally flash. Seems to go away after a bit. However, I can't get it to throw a code for whatever is causing the issue. 2004 Ford F150 146k miles on it

So I have had my FX4 for almost 10 years now. I have an xtra cab, bought new summer 2004 in Connecticut. Bought it had 5 miles on odometer, as of today has almost 117k miles. We just relocated this past weekend from CT to Manatee County, Florida, my wife followed me down in her 2010 Escape. Both trucks ran perfect..easy driving cruise control on 70 most of the way except for VA where there seemed to be a state trooper every 5 miles
anyway so overall I am satisfied with my truck since I've owned it. Changed oil every 4000-4500 miles without fail, 5-20 Motorcraft semi synthetic and FL-820 S filter is all it has ever seen. Engine doesnt burn/leak a drop of oil. As far as maintenace items and repairs, I looked through my records, here's what I've done:
1) rear axle rebuilt under warranty, clutch packs were shot at 60k.
2) brakes/rotors all around at about 50k, they still as of now have plenty of meat left
3) pinion seal went at about 90k
4) fly wheel had to be replaced at about 95k that was an expensive repair
5) replaced both front window regulators
6) replaced sliding rear window, under warranty, was leaking badly.
7) idler pulley replacement
8) exhaust rotted from just in front of muffler to tailpipe, replaced.
Also was told before we left CT that front coil spring was broken? I don't know about that truck suspension seems fine but will have it looked at.
Also normal maintenance did tranny flush 4x so far, fuel filter 4x so far, on 3rd set of tires, came with BFG rugged terrain, replaced at 62k with TOYO open country, they lasted 40k, now have Goodyear Wrangler LT's, so far excellent. Air filters, a light bulb here and there, and replaced battery after 6 years just to do it.
I have NOT changed the plugs yet truck does run great but I know what can and probably will happen, I feel comfortable with a dealer doing it, I'm not mechanically inclined enough to do it. I will have a little bit of a commute to work here, so I will probably get a ford Fiesta or a focus for the drive, but no way am I getting rid of this truck!

2007 F-150 Screw 5.4... Successful spark plug change. Well, sort of. I disconnected some of the coil clips/wires from the coils during the operation. Upon installation of the wires/clips, one of the clips did not 'click' into place.
Thinking the clip needed to be pushed/pulled, I bent the clip a bit and it snapped off! Being the slow learner that I am, a second clip also did not 'click' in place, and you know where this is going: I have two broken clips out of 8. After those two, I was much more gentle.
So, can these clips be replaced and/or spliced in? I'm thinking about just using nylon ties to hold them in place. So far, they are staying put just by being pushed in place, but these two do not seem very secure.
In the future, what is the correct way to make sure these things 'snap' back into place if they seem to not want to cooperate?
Here's a picture of the two 'press clips' that broke off....

I changed out my plugs. The plug connector on the #3 coil no longer snaps on. My only option is to use a small ziptie to hold it in place. Can cut it off and wired a new plug end on..

completely stock 2006 4.6, 230,000 miles, I purchased and can vouch for everything after 106,000.
Two separate issues...have had a slight ticking noise growing for about the last two years. Seems to get slightly worse near an oil change but that could be my imagination. It has finally gotten loud enough that my wife (who drives with the delicacy and observational skills of a Sherman tank driver) actually mentioned it to me the other day. It is directly related to engine speed whether the truck is in gear or not. I kind of think it might be a manifold gasket going out but am not sure. Am not very worried about it but...felt like I needed to mention it because of my bigger problem....
Truck has gotten very "cranky" on startup in the last week. Has a rough time finding an idle speed but typically sorts itself out after about 5-10 seconds. This afternoon it started idling rough at a stoplight. It got steadily worse and noticeable even at speed. Four stoplights and nine miles later it threw a code and coincidentally, I was in front of an Advance Auto. They read it and said the #3 cylinder was not firing. I bought an ignition coil, drove 15 miles home and changed it. From everywhere I looked online, this is the second cylinder from the firewall on the passenger side.
Had a little trouble getting it in and am not entirely sure it is fully seated in the slot, but I can't get it to go any further. Seems as tight as a couple of the others. I disconnected the battery to clear the codes, cranked it up and it seems to run "better", but still has a rough idle. Just test drove it about 12 miles and no check engine light but the idle has not cleared up. I think coil must be working fine because I have no issues at highway speed. Earlier, when I backed off the gas you would feel the miss very badly, but not as much when under a load.

I do not know the 5.4l 3v as well as my last 360ci dodge. It's a 2005 F-150 SuperCrew 4x4, got it cheap, and it's got issues. Got codes for misfire on cylinders 4 and 5 and Coil 'D' circuit malfunction. Obviously it has codes for limited power as well. was wondering how cylinder numbering goes and what coil is 'D'.

Changed my spark plugs and fuel filter but my fuel mileage seems to go down, used to get a average of almost 16mpg on a tank, now I'm down to 13.5mpg and also have the occasional stutter at different speeds/rpms. Is it time for new coils?

I just had the 3rd hubcap break on my '07 touring with 80K miles. They run $70+ each at the dealer. The aftermarket units the dealer sells don't fit the 16" wheels on the Touring model. Just curious if others have the same problem.

B5 Passat, it has the 2.8 and it has been having moments of shuttering so I did a scan and hit 3 engine falts, I did do a clear and rescan so these are new faults.
3 Faults Found:
17801 - Ignition Coil Power Output 1
P1393 - 35-00 - Electrical Malfunction
17802 - Ignition Coil Power Output 2
P1394 - 35-00 - Electrical Malfunction
17803 - Ignition Coil Power Output 3
P1395 - 35-10 - Electrical Malfunction - Intermittent
Right now my guess is the coil pack is going out or loose connection to the coil, this coil is roughly 8 months old so it kinda has me at a loss and hoping its not the coil.

I am trying to get my spark plugs changed and having a hard time trying to figure out how to get the coil packs out. I have done some research already but couldn't really find anything solid for the GS 460 specifically. Many people had useful information on the other GS models (300,350 etc) but since the 460 is not as common, I couldn't really find anything.
I read the guys use pry bars to wedge the motor a little to have extra clearance to pull the coil packs out but it seems the LS has a little more room to work with. On the GS 460 however, it is pretty tight and even using a pry bar I really do not believe the coil pack will have room to be remove completely.

Family friend's son has a 08 GTI, all stock. Engine caught fire reportedly due to #4 coil. Is there some recall on this?

Ok I have an f 150 04 fx4. 120k miles. I was checking a drip on the transmission cooler, and noticed my passenger side coil spring is broken 2nd coil from the bottom. Truck rides well, but obviously this needs to be addressed. Break looks old since it is rusted over, I probably relocated from new England to Florida driving this down 95 with this break, scary.

I've a 1993 2.3 and 1992 4.0 both with a/c systems down. On the 1993 Ranger I tried to loosen the evaporator tube nut to install the new accumulator now it looks like there's going to have to be a new evaporator. Without hardly any pressure that tube just twisted like it was nothing. Someone told me I have to spray it with wd-40 3 days prior to loosening it. I doubt that would even work. Hopefully removing the evaporator case cover under the hood won't be too time consuming because now I've got to. So I don't want to make the same mistake on my 1992 4.0. I need to change the accumulator, orifice tube, flush the evaporator, condenser, install the new hoses, and compressor before evacuating and recharging. Is there anything that makes it a breeze to loosening those evaporator and liquid line nuts without destroying the evaporator?

I've got a 2008 passat b6 estate 2.0 TDI sport. Car has highiles nearly 90k. The car needs a service but my main concern is that I'm experiencing a loss of power and the the coil shaped warning light flashes. This usually happens going uphill when the engine is warmed up. What this is and how much it should cost to fix without walking into a mechanic and paying over the top?

Do the 2010 5.4 motors still have any issues like the cam phasers or the spark plugs breaking upon removal? I'm looking at a 2010 F150 4x4 but I didn't want the headaches that might go with it since it has 80k miles....

Window washer nozzle break? My passenger side broke last Friday and then today when inspecting the driver's side it broke in the exact same place. They broke near where the nozzle that is inserted into the hose takes a 90 degree turn up through the hood leaving parts of the nozzle in the hose. I was able to squeeze the rubber hose with pliers to break up the plastic nozzle so that it would fall out. Attempts to grab broken nozzle piece with needle nose pliers were unsuccessful. Of course they waited too break until 8 months after my warranty expired but not a big deal. 10 minute install. I got the last two that the dealer had in stock.

Bolts breaking on the exhaust manifold. If so why isn't ford doing a recall on this problem I have a F350 V10 90K miles and 3 on the top drivers side are missing not sure on the passenger side. Is this a problem with all the ford engines I have never had this problem with any other truck or car I have owned.

I have a 'new to me' 2007 F-350SD super cab and need to run some wiring inside. What I don't know is how the heck the trim pieces are attached and how to remove them without breaking them! If it ain't held on with screws, nuts, bolts...

I have come to understand that Buick LeSabres are known for their issues with their ignition modules but I'm trying to figure out the root to the problem. I have an '04 LeSabre 'Custom'. I have had all of the coils and wires replaced and the ignition module. I had to replace some of the coils and ignition module twice since. I can already feel it going again.

I have a 2007 RX 350 2WD. Recently, the check engine light is on, as well we two other lights are on as well: VSC, TRAC OFF.
I went to Lexus and was told that the error code is P0356. I was told that the ignition coil F is problematic and need replaced. I was quoted 1 and 1/2 hours two 2 hours work and need $412 for the repair. Well, I went to auto zone and was told that No 2, 4, 6 ignition coils were on outside so that it would only take about 5 minutes to replace the problematic one with a new one.
I did the replacement indeed by myself after buying a new ignition coil. Initially it was fine and the light went off after a little while. However, after about 10 days, those three lights went back again. I check the ignition coil, it seems fine and I was told that it is very unlikely for a new ignition coil to go bad this quickly.
I was told that I may need to check my spark plug as well. BTW, when I start the car, the car is a little bit shaky.
