My 2004 honda civic hybrid has 8 spark plugs. The ones in the back of the motor look like they get much hotter and both times I have replaced them, all four in the back were really really loose.
View 2 RepliesRecently replaced head on my 95 civic 1.6 Vtec, i had to replace the head gasket a few years ago so i know what to do. My problem now is that it will not start and has no spark to the plugs, i have new plugs, wires, rotor and cap, even tried a new distributor but took it back since it changed nothing. I pulled a plug wire, removed the plug and plugged it into the wire, turned the engine over and no spark.I've checked voltage to the distributor with ignition switch on and as far as i can tell it's getting voltage to the distributor. But when i try to crank it the engine turns over but will not start. It is getting gas, i took the fuel rail off with the injectors and checked for flow. I've taken timing cover off a couple of times to make sure all timing settings were as they should be. I even went ahead installed a new ignition switch which made no difference. Waste of time and money. I've checked several times to make sure all electrical connections are good. I really hope this turns out to be a simple fix but right now i'm at a loss. ECM maybe?
View 4 RepliesI have with my F150 5.4 liter truck. I had the spark plugs replaced about 1 year ago. since then I have had 2 plugs back out and come loose. I would smell a faint gas smell first that would tell me know that it was happening. the first plug was if memory is correct either number 8 0r 7 on bank 2. this time its number 2 on bank 1.
I hope that my mechanic just did not torque the plugs correctly and all I have to do is tighten them. If that's not it. Could the spark plug holes be stripped and have to be re-threaded? And if so how us that done?
My 2004 honda accord will not start, there is no power to the spark plugs or to the coils.
View 3 RepliesI have a very well maintained 2005 honda odyssey with 150,000 miles on it. It typically gets 22 m.p.g. It started using an unusual amount of gas - was getting 12 m.p.g. Took it to the mechanic and turned out the gas pump was cracked. We replaced the gas pump and the gas line, and it was getting 14 m.p.g. Took it to another mechanic, and he said that the spark plugs were the problem as they were not official Honda spark plugs (we replaced them at around 110,000 miles). So we installed the official Honda spark plugs, but still no good. I have visited several mechanics and no one seems to know.
View 7 RepliesI 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?
I took a long trip this last weekend and before the return trip I checked the oil and realized I need some. I put two quarts which brought the level just about even with the top mark on the dipstick. the return trip was fine. Next morning I started the car and right away notice that the engine was misfiring. I checked the spark plugs and noticed that one of them was loose and had some oil in it. I checked the oil and now it showed the level to be well above the top mark on the dipstick. Could too much oil cause the spark plug to get dirty, get loose and misfire? This car is a 1997 and has 206,000 miles. This is the first time this has happened. Could the same thing happend with a 1999 Honda Civic?
View 10 RepliesHonda Civic 2008. Daughter sends att'd photo of passenger side, lower portion. (I will not see the real thing until Wednesday evening.) Does this need fixed, or can we just snip it off? (I can hope, can't I?). Who fixes it, glass shop or body shop? Is this a typical failure, or should we be concerned about vandalism or other malice? (What could they have been trying to get at? But the sharp bends look unnatural.)
View 18 Replies2000 Honda Civic DX, green, four doors, 91,000 miles. A few weeks ago I noticed that the steering wheel was loose when driving but only about 30% of the time--didn't seem to be related to whether the car was warmed up or time of day or speed, just that it happened when the car was moving. The steering wheel would have play when the wheels were pointed/driving straight and the looseness went away when turning. I brought it in to the mechanic and of course he couldn't get it to happen when he drove it. Replaced worn inner tie rods, did a power steering flush/replaced the power steering fluid and did a front end alignment. Drove fine for two weeks but then it started occurring again, this time even more loose/more play in the steering, still only when driving straight. Oh, just one time (so far) a few days ago it was loose when I was standing still at a stop light.

View 2 RepliesSo 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?
Sstripped threads using an impact to remove the plugs?
View 4 RepliesWhen driving, a pin fell out of the shifter arm under the car and now the shift stick is extremely loose and, although it will go into gear, it is almost undriveable. I have reinserted a pin, but the stick shift is still loose. I gave it a test drive and I drove about 10 feet in first gear, but when I put it into reverse, the car continues to move forward.
View 7 RepliesI 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 RepliesOk , 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.
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?
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.
View 7 RepliesI 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 4 RepliesMy 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.
