Ford Super Duty (1999-2016) :: Changing All 16 Spark Plugs?
Oct 24, 2015
My 2011 f250 has 92k miles, I want to change all 16 spark plugs.
Do the 6.2l plugs have problems breaking like the 3v engines did?
I think I'm going to pull the passenger fender liner to get to the lower plugs in the head.
How does the coil pigtail unclip? I looked at them briefly earlier and it looks like you pull the red tab back, then press down and pull on the pigtail but that did not work and I did not want to break anything.

Got a 2015 6.2. No where near time to change plugs, with alot accessories i have installed it would suck if the cab has to come off. Can the plugs be changed with the cab on?

Have a 5.4l that has multiple issues.
1st, fouled spark plugs on passenger side. All of them have a carbon glaze. That side of the engine seems dead. I checked the pcv valve and its fine. I took the head off to have fixed a broken exhaust manifold screw. After reinstall when The engine started and there was a lot of white smoke from the exhaust. Then it quit smoking. I was hoping it was from the new exhaust manifold i put on, guess not. I took the intake manifold off and noticed that there is an extra hole past the back of the manifold that the manifold gasket goes over but not the manifold itself. The pictures Ive seen make me think the setup is correct, but what is the extra hole for?
2nd, high idling. Around 2000rpm's. I am guessing its because of the right side not working for smoother idling?

OK changing plugs and boots on 2003 f 350 5.4 (I have a bad miss and mis-fire code) First time messing with these things. When taking out the coil over plugs it looks like somebody put die-elect grease up underneath the boot at the top where the spring and the metal prong touches together. I thought I just needed only to grease the plug on the sides to keep the boot from sort of melting onto the plug. And some boots had maybe a drop of water in them is this common or any concern? Might be condensation and water does conduct elec, so not that concerned, but these C-O-P's are new to me and thought I'd ask. I've searched here and read posts about changing of the plugs and C-O-P's but don't remember any water boot coming up.

I'm gonna change plugs , hoses, belts and fuel filter on my 08V10. Hoping it works with the mpg.
Anything else I should look for or do? Is there anything I need to know about changing the fuel filter?

I am changing the plugs in my 98 e150 today and I was thinking it was a .54 gap and 13 ft/lbs to tighten them. That sound about right?

I need to identify these random plugs under my dash. I think they might be for some sort of alarm or remote start unit and they seem to be tapped into the ignition wires. Suspiciously like remote start plug wires but I can't figure out what unit they would be for?

Went to hook up my trailer today and both the trailer plugs do not work. I checked the fuses and all is well. They worked fine the other day but now they don't work at all. I confirmed this by hooking up to another trailer and nothing. Also got another truck and went to trailers and it worked.
My truck has 19000 miles so it's practically new. I have never seen this. I called dealer but they can't see it til next week and I need the trailer brakes and lights. Where could I look or what could the problem be?

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 have an 01 F250 with a v10. Driving through heavy snow in 2013 a plug blew out. Should I expect this to happen again if I do some heavy hauling and should I do something preemptive?

My '99 was running rough - coughing/spitting/sputtering when under a load - especially at lower idle/rpms and going up inclines.
Brought to mechanic and he put it on "the scope" which told him the #1 pack was bad. Replaced. Got it back and it ran better, but, then went back to the coughing/sputtering.
Replaced the spark plugs - OEM Motorcrafts. Seemed perfect for a wee bit, now I notice an occasional cough/spit but all in all not bad.
Curious: was it foolish to not replace ALL coil packs at time of plugs or is it ...acceptable to do just the plugs and then come back and do packs if needed.

My 2010 prius had been giving low mpg since the last three months. It has now 145K miles.when I bought it a year ago, it had 134K on it. I haven't changed the spark plugs, do they have any effect on low mpg? My mpg is about 39 now,but was 42_45 before.
What are the symptoms for the spark plugs to be changed?

2001 LS v8 .... What would cause the car to give off a strong smell after changing the plugs?

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.

I got the APR ECU Tune in June along with VW Racing air intake. Car runs great except... the engine is knocking under full load. The guy who did the install heard it right away but I just thought he was trying to up sell me. He suggested new spark plugs.
Well it's two (three?) months later and I've come to accept that I can't drive it in the 91 program anymore (I paid extra for the ability to switch programs - lucky!!). I was switching back and forth between 91 and stock and I can hear the difference.
Are spark plugs the likely fix, and how do I choose the right ones for my Mark VI Golf R? "one step cooler"??

I've been doing the 40k service to my R32, and was in the process of changing the spark plugs.
The first three went smooth with no problems, the next three however.... When I pulled the coil packs off, they were covered in rust and corrosion.
The inside of the block leading down to the spark plug (where the coil pack was) also had rust in it. I haven't pulled those three spark plugs out yet. What caused the rusting?
I assume I need to replace these three coil packs, and clean off the existing spark plugs before removing them. Is that a fair assessment?
I haven't had any trouble with misfiring or stalling. The car has been running great.

As I say in my first thread my 2000 4 runner don't start after I change the spark plugs. I don't get any fuel pressure from the fuel pump.

I am trying to change spark plugs and wires on my 2001 Impala with a 3.8 liter. I was able to get the boots off of the front plugs OK but I am having trouble getting a good grip on the rear ones. It seems like they have glued themselves to the plugs. Removing the boots?
