Continuing from this thread which I accidentally posted in the "main" forum.
I had trouble unscrewing the spark plug even though the advertised torque is only 13 ft-lb and the car is only 13K miles 1.5 year old.
I googled "spark plug stuck" and read some posts on line.
Lots of horror stories of broken spark plugs and stripped threads - big $ to repair.

Experienced lower mileage after changing the plugs at about 120k miles?
In the 10 months (23.6k miles) since I had the dealer change the plugs, I have averaged 43.3 mpg overall.
Went to change the plugs on an 02 f350, the bolt holding the plug wire boot on doesn't seem to fit any standard size socket. 7 is too big, 6 is too small. 1/4 is too small, 9/32 is too big.
View 14 RepliesI have a 2007 Prius with ~180000, which runs great. The mechanic shop I used for oil change suggest me to change spark plug because they are dirty. After the change, I found I cannot step on the gas pedal too hard for acceleration. The car will hesitate, choking or die if I try to accelerate too fast. But if I step on the gas pedal gently, and let it reach the desired speed in a slower way, it has no issue. I went back to the shop and they replaced with another set of 4 plugs, and no improvement. I checked air intake tube and it looks no leak, but really old. Other than that, the car runs great.
View 19 RepliesI have a small problem, the dealer that serviced my car just told me that my water pump was leaking and I was low on coolant. I can't remember when was the last time I checked the coolant level but when the dealer top off the coolant, he nearly used the entire bottle. Needless to say, I believe the radiator was pretty low on coolant.
Now I've never noticed a high temperature warning lamp or ever broken down. Today at 125,000 miles, I went to change my spark plugs. The 1st plug to the far left as you are facing the car has oil in the spark plug. This is freaking me out, could my engine be damaged from the low coolant?
I want to change spark plug, took connector of spark unit and took bolt M6 out, lifted spark unit but not enough clearance to remove the unit in order to use wrench for unscrewing spark plug. How it works?
View 14 RepliesToday I began to change the plugs on my '04 Camry 4cyl for the first time at a little over 100 thousand miles. The first plug I came to doesn't want to come loose. I started with a 8" ratchet, now I'm on it with a 12 " ratchet and it doesn't budge. I'm able to go up to 3' and almost anything in between with a breaker bar plus a cheater, but I've heard terrible tales of people who break off a plug. How much force can you safely put on a plug? how do shops remove stuck plugs?
View 14 RepliesHad a spark plug sleeve come out, the part with the hex head to turn the whole thing. Wonder if JB Weld put on the inside of this sleeve and placed back over the plug will hold enough to turn the plug and get it out after some more pb blaster?
View 4 RepliesI have a Ford Taurus 2004 and would like to change its Spark Plug. I am looking for instructions for doing so as 3 of the spark plugs at the back of the engine are under the manifold air-intake. I am looking for step by step instructions of how to reach to the spark plugs to the back.
View 9 Replies2004 passat 1.8t. How do I remove the coil packs on the top of the spark plugs, so I can repalce the plugs.
I unclipped the wire and unsure how to pull the coil pack off.
No bolts. can turn it and maybe pull, but doesn't budge and don't want to break.
I just picked up a 05 F150 lariat 5.4 2wd with a 177k on it. What the chances of these plugs coming out with out breaking? Any tips tricks to getting them out? Should I put motorcraft plugs back in it ?
View 6 RepliesI have a 2006 Fx4 with 60,000 miles. I wanted to change the spark plugs myself yet I can't seem to find were they are in the engine, I know how to take them out but I don't know how to get to them.
View 1 RepliesI own a v10 and am getting ready to assist a buddy out with his 05 5.4l. He wants me to change the spark plugs out. I have changed the spark plugs on my 04 v10. I think this is the year for went to the 2 piece spark plugs. Also what torq setting should I torq them to? Should I also use anti seize with them or no? Does the gap need to be set on the plugs? I dont have a book to go buy.
View 12 RepliesI was able to unlatch the two white hooks attached to the back of the rear seat and lift the rear seat up to about 45 degrees. What about the front?
View 1 RepliesI'm trying to replace the spark plugs of my 2006 Prius, but the deep well 5/8 socket attached to a 2 in extender just turns loose, as if it does not fit in the top of the spark plug. I tried also 3/4 and 13/16 but those don't even fit in the spark plug well. I tried in another spark plug to the same result. Problem to replace to spark plugs?
View 7 RepliesI just changed the plugs in my 05 stx 4x4 4.6L. Truck was running fine, never a problem but it has 105k so I figured id change them. #4 was the only one that gave me a little problem (besides being so tight). The coil and spring pulled off the boot, and I had to get a pair of pliers and get the boot off the plug.
I simply slid the spring back through the boot and replaced it once I had changed the plug. Other than that they all came out easily. I replaced with motorcraft plugs, and #5 did have what looked like some oil down on the threads when I pulled it out, but not sure if that's a big deal or not
Any way, I am torn between ordering new boots and changing them out, or just biting the bullet and getting 8 new coils with new boots attached. Truck runs fine, but does the usual buck/jerk under a load in overdrive now (never once did it before)...
I had first two spark plugs break off in my 2005 F150 before stopping. I ran five tanks of injector cleaner through using different brands of cleaner. The next six plugs removed without any issues.
Since then, I replaced 2 plugs after 25000 miles. Used one tank of injector cleaner and had no problem.
I would suggest that anyone planning on changing plugs run some injector cleaner through before the change. The cleaner seems to remove the carbon build-up around the plugs.
I have a 2002 prius that threw a spark plug and loosened the coil pack. The mechanic just reinstalled the plug and tightened the coil pack and said it was fine. Why it would throw a spark plug?? It was running fine, no warning lights, i just heard an unusual slight noise and opened the hood to check it out, and notice the loose coil pack over the first spark plug
View 2 RepliesI am getting a cylinder 5 misfire and this has been a "on again off again" situation since last August. I took it around to a few places and the general solution was to get new spark plugs. After doing a bit more research I was advised to change the coil cover. I did that and it fixed the problem. Then about 4 months later the light came on again. I happened to change the air filter and the light went off. I though great, problem solved! not so much, when i went to the mountains the other day the light came back on. I did my research again and I have decided to get the plugs changed. Its a 2005 f150 with 94,500 miles on it.
I am told its time to change them regardless. I started calling around and getting quotes and have been told by multiple shops that ford made the plugs in my truck in a bad way. They have been telling me to change them and breaking them is a 50/50 shot. THEN, when they quote me they charge a rate to replace them plus the plugs themself. If they happen to break one then the customer pays for the new one. Do the plugs would really break that easy and should I plan on replacing some of them?
So I was changing my spark plugs and 3 of 4 went smooth. but one of them was very tough to get out. after a little while it came out, but.... porcelain was broken up. looked down the hole and saw some pieces. Vacuumed it up with a small hose. saw the pieces come into the vacuum, but i don't think i got them all.
Started the engine and made a terrible rattle sound. turned it off and researched a bit. one hit was on here from a few years back, saying the car ran rough for a sec and then cleared up. Hoping it was kicked out the exhaust. I started it up let it run and it cleared up and idled smooth.
Drove it today and seems fine. Slight click noise when accelerating but not sure if that was there before or I am just being paranoid now. Called some places and they all said same...could have cleared through exhaust, stuck in catalytic converter, damaged the interior walls etc etc.
I have a F150 which has developed a miss or hesitation when driving. I took it into my mechanic and he told me this:
This year truck is famous for needing a tune up but the problem is that ford redesigned the spark plugs for these years of trucks. The problem is hat carbon builds up and when u go to remove them the plugs break and sometimes you have to take the heads off to get them out, he said that this would cost around I 2500 is one breaks!
So my question then becomes is this the norm for my V8 2005 Ford F150?
My truck has 85,556 miles on it.
