Ford F-150 (2004-2008) :: Misfiring On Cylinder 4 - Changing Spark Plugs
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 a 1987 Ford Ranger 2.3L, it's the truck I learned to drive in (stick at 13yo) and the 1st car I crashed too... So now this baby is almost 30 years old and recently had a minor restoration...
Engine was pulled out and all gaskets were changed, spark plugs, wire... All that stuff... It has been running pretty good, however last week a water line broke on the Left side near the spark plugs (if you are looking at the truck)
Since then It has absolutely Zero power. The slightest hill and even when pedal to the floor will lose power. Yesterday went from the start of a hill at 60mph in 4th to 20mph in 2nd because it didn't have the guts to go 1/3 mile uphill... I checked everything I could, and my brother took it to the exhaust guy who made a small hole on the Catalytic Converter and said it was good, but he could tell it was running too rich...
I replaced some of the vacuum lines last night, I found a lose one on the fuel pressure regulator (I think that's what it is, Its towards the engine firewall on top).
Idles beautifully, drives great, no rough shifting, pinging or knocking, no misfires. So that's what has me stumped... Runs great but just no power... Also before water line broke it was running fine with power...

Prius (2004-09) :: Necessary To Disconnect 12v Battery Before Changing Spark 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.
View 6 RepliesPrius (2004-09) Fuel :: 2006 Noticeable MPG Drop After Changing The Spark Plugs
Right now I am seeing roughly 41 MPG and that is after changing the spark plugs with brand new NGK Iridium's, Air intake filter and did an oil change since it was due for one. I have driven the car roughly 2,500 miles since all of this stuff was done and it just seemed to continue to drop to the 41 MPG mark.
What I have noticed though is that when the motor turns off it shudders and the when it restarts while the car is in park the car will roll back and forth slightly. I have also noticed that the car seems to struggle to get up to the posted speed while climbing an incline and also while the car idles in park or at a complete stop there seems to be a bit of a miss fire. Could that be caused by a bad coil? Because I have tried everything short of taking it to the dealer which I really do not want to do again and be told there is nothing wrong with it when I know there is.
Ford Super Duty (1999-2016) :: Changing All 16 Spark Plugs?
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.
Prius (Gen 3) Fuel :: Not Changing Spark Plugs Can Drop MPG?
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?

View 5 RepliesGolf VI R :: Engine Knocking Under Load - Changing Spark Plugs?
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"??
Golf V R32 :: Coil Pack Rust When Changing Spark Plugs
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.

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?
View 10 RepliesFord - Ranger :: Cylinder Misfire - Spark Plugs Keep Going Bad
I purchased a 2000 Ford Ranger last year. Within the first two months of ownership, the vehicle was having a cylinder 4 misfire. To fix it, I replaced the fuel filter, plugs, wires and cap - replacing the wires, plugs and cap fixed the issue. The issue went away for four months when cylinder 4 misfired again. I brought it to a repair shop and they again replaced the wires and plugs. The vehicle now has a cylinder 6 misfire.
There has to be something causing these plugs to continually go bad. Rather than just replacing the plugs again, I'd like to attempt to be proactive and fix the root of the issue. I've googled the issue and some of the forums seem to indicate a bad EGR valve.
Sonata NF (2006-10) :: Tiny Rattling Noise After Changing Spark Plugs / PCV Valve
So, I changed my spark plugs a couple of months ago and did the pcv valve swap as well. Now I have this high pitched rattling noise, like a tiny chain rattling. It is coming from the engine bay - in the area between the throttle body and the firewall. At least that's where I can hear it.
It does it quickly right after I start the engine (though I am certain it is not a timing chain issue)...I had that fixed a while back. Also it doesn't sound like the timing chain tensioner noise.
I am thinking maybe the pcv valve that I swapped out. I remember reading that a new one should make some noise when you shake it...an old, gunked one would not rattle if you shook it in your hands. Consequently, this noise sounds a lot like if I would shake the pvc valve back and forth very fast.
It happens intermittently on idle....and when I rev the engine, it will also make the noise while the RPM falls back down. Since this happened literally right after I did the spark plug change and the pcv valve, my guess is it's that. Maybe I didn't install it correctly.
Ford Ranger / B-Series :: New Plugs Now Truck Running Rough
Although my lil' truck (2006 Ranger XLT, 2WD,with 4-cyl / 5spd, and 115K miles) has been running just fine since I bought it about a year & 5K miles ago, I suspected it still had its original spark plugs and I figured I should change them before problems arrived.
As I suspected, the plugs that I took out looked to be original. I measured their gap and they all had excessive plug gaps - around 0.052" gap. I installed the four new AUTOLITE APP104 (double platinum) and checked their gap, and they were a bit tight at 0.042". My book says they should be at 0.044" gap. But I installed them at 0.042 anyway, figuring they'll burn wider in time.
One by one, I smeared a small bit of never-seize on the plug threads & at the plug-to-cyl head tapered edge. I smeared a dab of Dielectric Grease around at the top of the plug to ease the plug wire re-install and hopefully calm any possible arching. The plug wires came off the plugs easy enough and went back on just as easy.
I hit the key and the engine fired right up. It idled rough as expected. However, it continued to idle rough and if I raised the RPM level, it would respond, but still ran rough. It is throwing a 'Check Engine Light' on the dash cluster now - whereas it wasn't prior to the new plugs.

2000 flex fuel 3.0 4x4 .
I have checked the fuel pressure and it is good.
I have good strong spark to each plug.
I have cleaned each plug. and i have a no start situation.
Does the cam position sensor control the injectors firing? Or does it control the firing order for spark? I can crank her for a few cycles and then pull the plugs and they are dry,with no fuel smell.
The motor has a cam position sensor and a crank position sensor. ijust need to know what each one controls.
Ford F-150 (2004-2008) :: 2007 - Spark Plugs Replacement Every 60k?
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.
View 3 RepliesFord Ranger / B-Series :: 2001 - Turns Over Great But Will Not Start After New Plugs And Wires
2001 Ford Ranger 4.0 - 250k miles had the original plugs and wires ....
First things first - I changed them one at a time and confirmed the truck started and ran after each one was changed. I changed all the plugs on the drivers side with no issue. 4,5,6 ... Then I changed plug 3, rear passenger side plug closet to the firewall.
Truck will not start, turns over great, but will not start. I have confirmed I am getting spark. No clue what could have changed, I just pulled out the old plug and wire put in a new one and it wouldn't start.
My father-in-law said if you have spark check fuel. I recall seeing a post about someone breaking a cable for the coil pack but i have checked and i see nothing broken.
