Camry :: 2009 SE 4cyl - 165,000 Miles On Original Spark Plugs (Highway Driving)
I have an 09 camry se 4cyl with 165k. I believe the service interval on the plugs is 100k. However, 75% of my miles are from highway driving. Plainly put, the car still drives like brand spankin new and get gets 30mpg hwy. This tells me the plugs are doing their job just fine. What concerns would you have if any?

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) :: 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?
Prius (2004-09) :: Hybrid Warning Light Came On When Replaced Spark Plugs
My husband just replaced the spark plugs in my 2005 prius with 174,000 miles (also replaced the right headlamp bulb). When I started the car, the PROBLEM check engine light Hybrid Warning Light came on.
Owner's manual says take it to the Toyota dealer. The dealer is 50 miles away. Is it safe to drive it the 50 miles? It drove okay up and down my driveway.
Prius (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.
Toyota - 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?
Prius C :: Connector On The Spark Plugs Has Different Color

Pontiac - Grandprix :: 2004 - Cylinder 3 Misfire And Gas On Spark Plugs
Ok , i have a 2004 Pontiac Grand Prix GT V6 GM 3.8, my car didnt have any misfires until after i changed my Lower Intake Manifold Gaskets. After changing the gaskets and putting everything back together. The car ran fine. The next day i took it an hour and 30 min away, while driving there it started misfiring and shaking,rough idle at an hour into the trip. The check engine light went to blinking. The Next day i drove it all the way back home in the condition. Put code scanner to it, and received P0303 "Cylinder 3 Misfire":
So i automatically assumed it was the coil pack because i just installed new wires and plugs a week before changing Lower Intake manifold Gasket. Bought new coil pack. Still getting rough idle and P0303 code. So i decided to take a look at Cylinder 3 Spark plug and it was dry black, carbon fouled:
So went and bought new spark plug, installed it, started car and still rough idle and misfiring. Took the new spark plug out and it had been FOULED also ( DRY BLACK AGAIN). So i was told to switch a coil pack around. I did it and the started car, took away some of the rough idle, car actually wasn't misfring or shaking, would run smooth for about 5-8 seconds then start misfiring (Didn't that until i switch coil packs around).
Next Decided to pull out the rest of the plugs from the back and all of them were WET with GAS!! and 2 Spark plugs are just dry fouled!! (Cylinder 3, Cylinder 1). If I can figure this out i will fully have my car back to running correctly.
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.

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?
