Prius (Gen 3) Fuel :: Not Changing Spark Plugs Can Drop MPG?
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?
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.

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 RepliesGolf VI R :: Engine Knocking Under Load - Changing Spark Plugs?
I got the APR ECU Tune in June along with VW Racing air intake. Car runs great except... the engine is knocking under full load. The guy who did the install heard it right away but I just thought he was trying to up sell me. He suggested new spark plugs.
Well it's two (three?) months later and I've come to accept that I can't drive it in the 91 program anymore (I paid extra for the ability to switch programs - lucky!!). I was switching back and forth between 91 and stock and I can hear the difference.
Are spark plugs the likely fix, and how do I choose the right ones for my Mark VI Golf R? "one step cooler"??
Golf V R32 :: Coil Pack Rust When Changing Spark Plugs
I've been doing the 40k service to my R32, and was in the process of changing the spark plugs.
The first three went smooth with no problems, the next three however.... When I pulled the coil packs off, they were covered in rust and corrosion.
The inside of the block leading down to the spark plug (where the coil pack was) also had rust in it. I haven't pulled those three spark plugs out yet. What caused the rusting?
I assume I need to replace these three coil packs, and clean off the existing spark plugs before removing them. Is that a fair assessment?
I haven't had any trouble with misfiring or stalling. The car has been running great.

I am trying to change spark plugs and wires on my 2001 Impala with a 3.8 liter. I was able to get the boots off of the front plugs OK but I am having trouble getting a good grip on the rear ones. It seems like they have glued themselves to the plugs. Removing the boots?

My 2011 f250 has 92k miles, I want to change all 16 spark plugs.
Do the 6.2l plugs have problems breaking like the 3v engines did?
I think I'm going to pull the passenger fender liner to get to the lower plugs in the head.
How does the coil pigtail unclip? I looked at them briefly earlier and it looks like you pull the red tab back, then press down and pull on the pigtail but that did not work and I did not want to break anything.
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?
View 14 RepliesSonata NF (2006-10) :: Tiny Rattling Noise After Changing Spark Plugs / PCV Valve
So, I changed my spark plugs a couple of months ago and did the pcv valve swap as well. Now I have this high pitched rattling noise, like a tiny chain rattling. It is coming from the engine bay - in the area between the throttle body and the firewall. At least that's where I can hear it.
It does it quickly right after I start the engine (though I am certain it is not a timing chain issue)...I had that fixed a while back. Also it doesn't sound like the timing chain tensioner noise.
I am thinking maybe the pcv valve that I swapped out. I remember reading that a new one should make some noise when you shake it...an old, gunked one would not rattle if you shook it in your hands. Consequently, this noise sounds a lot like if I would shake the pvc valve back and forth very fast.
It happens intermittently on idle....and when I rev the engine, it will also make the noise while the RPM falls back down. Since this happened literally right after I did the spark plug change and the pcv valve, my guess is it's that. Maybe I didn't install it correctly.
4Runner/GX470 :: 1998 - Lacking Fuel To Run / No Flow With The Key On
My 4Runner died in the road yesterday. It has fire but lacking fuel to run. I took line off of fuel filter and have no flow with the key on, I do have flow and pressure when I turn key to start. Should the fuel pump run with just key on. Does it need to be running to keep fuel pump on. It tries to start but is starving for fuel.

I just did my winter hard top for the season, hooked up the plug for the rear heater and it works but it's cranking out cold air even when I am up to running temperature. The front heater is blowing lots of heat. Am I missing something? Is there something other than the plug I need to hook up?

My 1992 3.0L V6 is showing it's age. My 4Runner problem is getting worse by the day. It started the day after I bought it. My truck won't accelerate with the RPMs over 3k. My truck smells like fuel. The fuel filter is 3k miles new. I can't get it to start like it used to now. It will take me at least three cranks for it to turn over. The battery is new too... less than one year old.

This 96 4 runner's rear wiper and rear window has stopped working. I can only assume they stopped at the same time as the truck doesn't belong to me, I was just asked to see what it would take to fix it. I've looked it over and see no fuse and don't really have a clue where to start looking for the culprit of the problem.
View 2 RepliesHonda - Odyssey :: 2005 - Replaced Spark Plugs / Gas Pump / Gas Line Still Getting 14 Mpg?
I 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 1 RepliesFord Escape / Hybrid :: 2001 - MPGs Dropped - Spark Plugs / Fuel Filter?
Im noticing my mpg dropping in the past couple of months. I usually get 19 or 20 in town, and up to 23 on the highway. Now im lucking if I get 16 or 17mpg.
I have a 2001 escape XLT. 6cyl 4x4.
I changed the spark plugs, coils and fuel filter about 3 years ago (almost 40k miles ago).
The car starts fine, seems to idle fine, seems to accelerate ok. The only thing that is off is the MPG.
I dont just want to throw money at parts. Which one should I replace?
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?
Ford F-150 (2004-2008) :: 2005 - Changed Fuel Filter / Spark Plugs / Battery Now Idle Roughly?
I have rough idle problem after changing spark plugs, fuel filter and battery. There was no rough idle problem before this work was done. What could be wrong. Once the speed is above 20 mph it seem to run fine but at stops it vibrates and seem like it may stall!
