Ford - 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.
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 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?
Corolla :: Spark Plugs In Left Hand Cylinder Burning Up
I have been burning up spark plugs in the left hand cylinder (when facing the engine from the front). I have burnt up two plugs in a month in that cylinder. I have low compression in that cylinder and my oil consumption is high as well (1QT every 300 miles). My question is, is the oil fouling plugs and the oil consumption connected or is there other things I should look into?
View 2 RepliesPassat (B6) :: New Plugs / Coils - Misfire On Cylinder 2 Or 4
Replaced plugs and coils after I got a misfire on cylinder 2. (cheap made in china coil packs off of autoparts warehouse)
Also, plugs had 30k miles on them with original packs. Got it again.
Replaced coil on cylinder 2. Got it again.
Bought Denso double platinums. Got it again.
Moved coil packs around. Misfire on cylinder 4.
Checked plugs, good dry non corroded. Its always 2 or 4.. not 1 or 3
Slow drive with less than 30% gas pedal action it runs "ok". If I go uphill or need to step on it, not happening. Bucks like a mule.
I dont think its the fuel injector... Ordered the red audi packs off europaparts. Might need to check connections. what do i do?
I've been also reading that it could be the cam follower. I'm willing to check it and then force the dealer to fix it under the extended warranty, but if its broken I cant put it back in. The dealer is 50 miles from me.
It happened a morning I was out of gas and used .... regular! But did put in super right after that. I had spare regular gas in a container (fresh) for the generator.
Then used fuel additives. I have also been using fuel additives every other fill up just to protect injectors. I know it wont do anything other than that because of direct injection.
Golf IV / Jetta IV :: Misfire On Cylinder 3 - Replace All Plugs?
After getting some misfire and hesitation (code reading says misfire on cylinder 3), it looks like I'll be doing my first spark plug change on my 24V VR6. I've ordered all of the plugs, and have made sure that I'v got all my tools on hand. Hopefully, the DIY's I've found on Vortex will be as useful as they look .
My car has 163K on the clock, and spark plug change has been on my short list of to-do items, as I'm not sure of the maintenance history of the car. Hopefully, the spark plugs will do the trick, but coil packs will be done soon too.
Would it be OK to change just the coilpack on cylinder 3 and leave the others alone if they are all working OK? Or just shell out the cash to change all six at once?
Grand Prix :: 08 - Misfire And No Spark On Cylinder 6
Driving last night and my 08 died after searching I found the ICM fuse was blown. I replaced the fuse and now it has a misfire on cylinder 6. I have changed the coil with no luck. I replaced the plugs and wires about 2 weeks ago and I don't find any problem with the plug or wire. I checked at the coil and there is no spark at all on cylinder 6. I was thinking the ICM is bad but was wanting some opinions.

So I have an 04 grand prix. Every morning I get to my car and it won't start. The lights work. Locks. Etc. I have to put it on the charger for awhile to get it to start. Sooo could it possibly be a bad connection to the starter or is something just draining my battery enough to make it not start? I just had a lot of after market wiring removed and it didn't do this until it got cold out.
View 5 RepliesToyota - Corolla :: 2002 - Tighten Spark Plugs To Same Torque Specifications As Regular 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?

View 2 RepliesPrius (2004-09) :: Spark Plugs Shot At 38,000 Miles
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?

View 6 RepliesPrius (2004-09) :: Changed Spark Plugs But Gaps Were Little Out Of Range
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?
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.
