Bought my car three weeks ago. I was looking around under the hood and noticed that the color of the connector on the spark plugs is different. Two are grey and two are black, in alternating order. What's up with that?
View 5 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?
My 2010 prius had been giving low mpg since the last three months. It has now 145K miles.when I bought it a year ago, it had 134K on it. I haven't changed the spark plugs, do they have any effect on low mpg? My mpg is about 39 now,but was 42_45 before.
What are the symptoms for the spark plugs to be changed?
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?
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 RepliesJust 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 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.
I have 60k on a 2010 Prius III. my mileage is slowing dropping, i am thinking about installing new plugs.?
View 7 RepliesRight 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.
Changed the spark plugs on my 2006 Camry today. Everything went smoothly and quickly except for the fact that I broke all the little keeper clips on the connector plugs that connect to the coil packs. I called my Toyota dealers and one said I had to replace the entire wire harness. The other found the connector plugs for around $8 each. Will the broken clips be a problem with the connectors eventually coming off from vibration if I don't replace them? I'm not sure how to replace the connectors if I go that route. How to go about replacing the connector plugs?
View 7 RepliesScheduled maintenance for changing spark plugs for my Camry 2004 2.4L is either 120k miles, or 144 months (12 years). My Camry reached 12 years first. In removing the coil connectors, 3 of 4 holdowns cracked off. I guess not so surprising after 12 years subject to engine heat. I'm NOT going to replace the connectors. Looking for a patch for this problem? Duct tape will just result in adhesive getting everywhere it shouldn't. Maybe there's a high temperature "crazy glue" I could apply at the connector interface that will last another 12 years, or 120k miles?
Otherwise, I'll use the "hope adhesive". That means I'll just hope the connectors don't work loose at a bad time.
I am having a problem where my spark plugs keep going out. I changed all the plugs, wires and coil pack on my 2001 Windstar and within a few months my van was running on 4 or 5 cylinders instead of 6 and this isn't the first time it has happened.
View 14 RepliesI have a 2001 saturn sl 2 and I noticed some oil around all the spark plugs. The engine seems to be loosing oil a little bit as well, about a quart a week. Its not buring it or leaking that I noticed.

View 10 RepliesI was having some problems and one of my friends told me to post up here before I went and saw my mechanic. So my car isn't starting (its a 06 r32). Now I've gone through a whole list of things and what I have worked out is that it is the spark plugs not firing (none of them are) although they are all brand new and were working not too long ago.
Battery is fine and fuses look good no warning symbols on the dash so I'm at a bit of a loss as to what it could be. Relays? Coils?
I was thinking about change my spark plugs on friday so today I went to check the ones the car have open the hood took the engine cover out and the ones on the sides, I see 6 wires 4 going to the left side(air intake side) and 2 going to the right side (where the oil fil cap is) so I say think this should be the spark plugs wires. I take one of the left side wires out and is cover in oil so I keep taking the other out one by one and all of them have a lot of oil I can't even see the sparks plugs. All the wires have numbers on top 1 to 6. I say this have to be the wires cause I don't see any other place where the plugs can be located at. The car is a 99 v6 fwd...
View 7 RepliesI would like to have a look at the condition of the ignition plugs in my V8 Phaeton.
According to the service plan, it's already time to change them and it also seems that the car has lost some power when accelerating.
Is it even possible to change them with the 'usual' knowledge (knows how to change a tire and so on) or should I better go to a professional.
Had issues with TBI, rebuilt. Had some starting problems after truck sat for 1 day or more, but would start after a few tries. At one point when it was particularly stubborn, starter lead vibrated off. Once reconnected, truck started, ran fine, but had some electrical humming & radio interference. The starting issue continued with some low rpm stumbling, when driving check engine light would come on at cruising speeds and go off 7-8 seconds after letting off gas.
Had 1 day lest week when I drove a bit more then normal (150+) but ran fine other then engine light. Next day started, but ran horribly rough with violent back fires. At one point stalled and would not restart. It looked and acted like it was flooding itself out and poor spark. Less then a year I replaced cap, rotor and coil. Now I have done all new plugs and wires. Now it appears I have no spark. I had been in the dash messing with the blower motor relay 2 days prior to the stalling and not starting.
Does the ECM control spark? Cant it go bad slowly? And if I had to do alot of cranking of the engine to get it to start, would that have any thing to do with it going bad?
I don't have a torque wrench. I just have a spark plug wrench. I changed my own spark plugs. I don't like taking them out and putting them back in. I'm not sure if I got the torque right. What should I do?
View 1 RepliesI have a 2000 Jetta 2.8 VR6 (the 6-cyl) with 128k miles and I have oil on my spark plugs, only on one bank of the motor (the bank closest to the bumper, if that makes any difference). I am aware that it is most likely a leaking or worn out valve cover gasket, and I have a replacement and am prepared to replace it. What I need to know, and I can't find this exact part anywhere, is do I also need to replace the spark plug tube seals??? The gasket I ordered did not come with any tube seals, I can't find this part on any auto parts website at all, nor have I been able to locate anything useful on this, or any other, website. I know the 1.8 has plug tube seals, and they come with the gasket, but does the 2.8 also require tube seals? I imagine it would, but I just don't know.
View 2 RepliesI have a '63 Buick Wildcat that has been sitting for 17 years. It has 2 spark plugs stuck in the motor. I got the other 6 out with liquid wrench. The other 2 have been soaking in liquid wrench for 2 weeks and I have been using a 3/8 drive spark plug socket, but still unable to get them out. How to get them out?
