Ford F-150 (2004-2008) :: 5.4 Liter Truck - Spark Plugs Coming Loose
Jan 2, 2014
I have with my F150 5.4 liter truck. I had the spark plugs replaced about 1 year ago. since then I have had 2 plugs back out and come loose. I would smell a faint gas smell first that would tell me know that it was happening. the first plug was if memory is correct either number 8 0r 7 on bank 2. this time its number 2 on bank 1.
I hope that my mechanic just did not torque the plugs correctly and all I have to do is tighten them. If that's not it. Could the spark plug holes be stripped and have to be re-threaded? And if so how us that done?

My 2004 honda civic hybrid has 8 spark plugs. The ones in the back of the motor look like they get much hotter and both times I have replaced them, all four in the back were really really loose.

My '07 had the check engine come in the other day, engine misfire. I took it to the dealer hoping it was a coil, due to the 100,000 mi warranty from Ford I was hoping would be covered. Sadly, and of course, all coils tested fine, turns out 2 plugs were bad. They replaced all 8 plugs, plus a plug boot. Not one plug broke (truck had 80k on it) so no extra cost there. So much more, but peace of mind that all the plugs are new one piece plugs is great. He recommended that they should be replaced every 60k to avoid any issues.

I am a newbie here, and also a new owner of a 2006 F150 XLT 4X4 with the 5.4 engine. It has 68K miles on it and looks to have been well cared for. I have a couple questions. First the truck is runnig great, no problems. I have read the threads regarding the spark plug issues and was looking for an opinion about changing them. Should I wait until I have problems, or due to the age of the truck, should I go ahead and attempt it soon? Also, I would like to find a used cap for the bed. I have the 6.5 bed, and wondered what range of years would work with my truck.

2004 5.4L ... Codes indicate a firing issue on #4 cylinder, figure it's the coil pack. They bought truck used a few years ago and plugs have not been changed since they have owned it. I was going to change plugs while I was under the hood. While checking threads on this engine I picked up on plugs being a major job unless you know the tricks. So what tricks do y'all have up your sleeve to keep from breaking plugs?

I've recently had a small issue with my truck missing under hard load. If you're going around 40 MPH and push it down like merging it will kick back and forth and sputter and then start hitting fine again after a few seconds and move on. Possibly bad sparkplugs and/or wires?

I changed my spark plugs now I got a miss and rough idle .#2 and 6 seem to be the ones that miss the idle don't change when I unplug the coil , I take coil off and put it next to the motor it sparks ! I put everything 3 plugs and got about 200 miles on them and 3 out of 8 had melt downs and left me on the side of the hwy. I got autolights in it now but it got a miss and rough idle ! Did I not do something right ?

I have rough idle problem after changing spark plugs, fuel filter and battery. There was no rough idle problem before this work was done. What could be wrong. Once the speed is above 20 mph it seem to run fine but at stops it vibrates and seem like it may stall!

I have a 2008 Camry, 2.4L, and used the spark plugs change DIY sticky and it seemed to go painlessly. However, after the new spark plugs, the car seems to idle rough. It has 95k miles, and I did the following in the same tune-up:
1. Changed Oil
2. Replaced Air Filter
3. Changed Spark Plugs
4. Cleaned Battery Terminals
5. Cleaned MAF Sensor
6. Cleaned plugs connecting to ignition coils
I used OEM Toyota plugs, and even called the dealer to see if the gap needed to be set. And they affirmed me that the gap is preset on these plugs.

2004, 4L, sohc - Is there any issues or problems changing spark plugs?

I am changing my own spark plugs for the first time. I have a spark plug wrench, dielectric grease, anti-seize compound etc.
I have a Haynes manual for my 2002 Toyota Corolla. The book was written before Irridium plugs were used. Should I tighten the spark plugs to the same torque specifications as regular plugs? The book says 158 inch pounds. How do I know I have tightened them to the right amount?
How do I avoid cross threading the spark plugs? What happens if you cross thread the spark plugs (assuming the car seems to be running fine)? Would I need a new engine or expensive repair when it is time to replace the spark plugs again?

I just changed my spark plugs the other day and since then my engine is hard idling and skips and jumps while I'm driving it. I'm being told I either need to change the spark plug wires or the coil packs. So my question is which do I need to change? And is there anyway to test which one I need to replace?

This past Sunday, I replaced the spark plugs on my 2008 Toyota Camry CE, following one of the sticky DIYs. My car has approximately 107,xxx miles.
Last night on my drive home from work my CEL came on. First time seeing a CEL light since my BMW days, . Luckily, I have a OBDII scanner at home and after running the scanner, it gave me the following trouble codes:
- P0101
- P0172
I went ahead cleaned the air filter (I have an Injen SRI installed).
After doing some research on the interwebs, I have concluded that this code has to do with the MAF. Time permitting, I am going to clean the MAF sensor later tonight. In the meantime I reset the CEL, to see if it will come on again.
My only question, which I am unable to find an answer to, is:
Can there be a possibility that the P0101 and P0172 trouble codes be related to me replacing the spark plugs, or is this just a mere coincidence?

I purchased a 2006 Lariat crew cab 4x4 back in early feb... since then, I've been on the Interstates a little more than usual ( traveling back home.. dad had a surgery 3 hours away) . . . anyway, the truck gets kinda loose feeling when coming onto bridges and off of them, almost like the back end is swaying and the tires are leaving the ground in the front.. my steering wheel gets loose for a split sec. When I bought the truck I wrote this off as bad tires.. it had some over inflated BFG stock looking tires and where too small.
now, I have new wheels and new tires one size up on the tire. While the ride is great off any bumps.. the second I hit a bump it gets squirmy... I had a guy look at the shocks, he said the seemed ok.. could it be possible to have the wrong shocks on ?
My 2004 crew 4x4 did not do this.. so I know its not a characteristic of the truck. Tired of feeling like I am driving on ice... which is how I lost my 04. My first guess was the Shocks... I bought a level kit for my 04 and never got to put it on... so, it may work out to replace them while I am at it.

So in the middle of a road trip 9 days ago my check engine light came on. I was 2 hours into an 8 hour round trip day trip. I was close to a Toyota dealer so I went there for a diagnosis. They said my MAF bank 1 sensor 1 needed replacing but they didn't have the part so couldn't do the fix but I'd be okay to complete my trip. They collected their $100 and sent me on my way with no warning lights on.
30 minutes later the check engine returns and I'm unable to accelerate. I stop the car for a bit and then am able to continue my trip. I have one other incident where when I was traveling at a low speed, I lost all power. I was able to drive home 4 hours with the check engine light on but no further issues with the exception that I got less than 20 miles a gallon for the trip.
Took my car to a local Toyota dealer. They independently diagnosed that the same sensor needed replacing. They also told me that my spark plugs were shot. According to the service rep, they looked like they were from a car with over 100,000 miles.
Is this possible given the description above from the first time my check engine light came on?

I got the plugs for my '06. I hope to put them in in a day or 2. My question is: is it necessary to disconnect the 12v battery to do this? I've changed plugs in other cars without doing so.

Ok , i have a 2004 Pontiac Grand Prix GT V6 GM 3.8, my car didnt have any misfires until after i changed my Lower Intake Manifold Gaskets. After changing the gaskets and putting everything back together. The car ran fine. The next day i took it an hour and 30 min away, while driving there it started misfiring and shaking,rough idle at an hour into the trip. The check engine light went to blinking. The Next day i drove it all the way back home in the condition. Put code scanner to it, and received P0303 "Cylinder 3 Misfire":
So i automatically assumed it was the coil pack because i just installed new wires and plugs a week before changing Lower Intake manifold Gasket. Bought new coil pack. Still getting rough idle and P0303 code. So i decided to take a look at Cylinder 3 Spark plug and it was dry black, carbon fouled:
So went and bought new spark plug, installed it, started car and still rough idle and misfiring. Took the new spark plug out and it had been FOULED also ( DRY BLACK AGAIN). So i was told to switch a coil pack around. I did it and the started car, took away some of the rough idle, car actually wasn't misfring or shaking, would run smooth for about 5-8 seconds then start misfiring (Didn't that until i switch coil packs around).
Next Decided to pull out the rest of the plugs from the back and all of them were WET with GAS!! and 2 Spark plugs are just dry fouled!! (Cylinder 3, Cylinder 1). If I can figure this out i will fully have my car back to running correctly.

Just got done changing the plugs on my new to me 2008 Prius. They were in there a little tight and the crunching noise they make at first is a little disconcerting, but I'm thinking it has something to do with the coating NGK puts on their plugs.
Anyway, everything went smooth and I took my time and used tips I read about here. I've worked on cars since I was 16 and have rebuilt motors and completely restored a 1956 Chevy, but this Prius is a different animal. I think in the end though we are going to be friends...
Here are some pics of the old plugs. The gaps were a little out of range, and there was some wear, but 148k on spark plugs and the car still runs good?

My 2004 honda accord will not start, there is no power to the spark plugs or to the coils.
