Ford F-150 (2004-2008) :: 2005 STX Misfiring After Spark Plug Change
I 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)...
Ford F-150 (2004-2008) :: 2006 - When To Change Spark Plugs Normally?
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.

my wife drives a 2008 toyota camry 4cyl. she has about 86000 miles so i figured i would do a little tune up. change plugs, filters, injector clean, etc. while changing the plugs i seem to have broken 3 of the 4 pressure tabs on the plugs that plug into the coil. for the time being i have the pressure tap electrical taped very tightly onto the plug. What I should do? or is that common to for those to break off. I didn't even really use a lot of pressure either.

Just replaced spark plugs in my 2007 Sonata V6 and noticed that my MPG has dropped from about 24 to 19! I used NGK Iridium plugs, and also changed the PCV valve at the same time. Mileage is 136,000. Could the internal computer (that does the MPG calculation) have gotten messed up by all of the disconnecting/unplugging that I had to do to get the surge tank off? (BTW - the engine runs great - just the MPG went way down).

Prius (2004-09) :: Gas Pedal Too Hard For Acceleration After Spark Plug Change
I 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.

Had 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?

I dont have a book to go buy.

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.
Ford F-150 (2004-2008) :: 2005 - Cylinder 5 Misfire - Spark Plug Replacement?
I 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?
Ford F-150 (2004-2008) :: Loss Of MPG After Plug Change
I have an 04 F150 5.4 w/67k. Just changed the OE plugs. While I had it in the garage also cleaned the K&N air filter. Truck runs great but I lost about 3 MPG. I was getting 16 all around and am now getting about 13 under the same conditions. I bought a Purolator air filter and switched it with the K&N but there had been no difference. I used Champion plugs as the replacements. Truck ran great before and runs great now.

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.
Ford F-150 (2004-2008) :: Trans Fluid Change - How To Get To Converter Plug

View 4 RepliesFord F-150 (2004-2008) :: Running Rough And Skipping After Plug Change?
I just completed a successful second spark plug change, using Motorcraft SP515 plugs just like last time. After reconnecting battery and starting engine, it ran poorly throughout a short road test. Felt like it was skipping. Checked under the hood and found that the #2 fuel injector was disconnected, so I reconnected the injector.
I took another short road trip and it still ran poorly as if skipping. So, this time I disconnected the battery for several minutes while removing the #2 plug thinking I may possibly have fouled the plug by the injector not being connected. I also checked all of the other injector and coil connections. Reconnected battery and took another short trip. It still runs poorly. No codes yet.
Ford Escape / Hybrid :: 2011 V6 Won't Start After Spark Plug Change?
I have a 2011 Escape Limited 3.0l V6 AWD. Did a spark plug change at 115k miles for the first time per dealership recommendation. Got new plugs from dealership.
Was pretty cut and dry to replace. Did not check gap on plugs as was told they are not adjustable per dealership. Put pea sized amount of dialectric grease in the COPs and then fitted the plugs into several times with a little spin to coat evenly. Installed plugs to 11 ft.lbs. and reassembled all components without issue. Installed them one at a time so as to not mix up the coils.
I did break the 90-degree nylon quick disconnect for the fuel line that connects to the fuel supply manifold and had to purchase a new hose assembly. Reinstalled without issue.
Went to start up and engine cranks (hiccup sound) but does not turn over. The sound is weak and not a throaty crank like an engine should give. Check engine light flashes on dash and issues a frequent tone also.
Wondering what the issue is? Are they the wrong plugs? Improperly gapped? Possible the fuel line did not pressurize and there is no fuel getting to the plugs for ignition? Kind of stumped as it was a pretty cut-and-dry replacement (if such a thing is possible).
