Golf V R32 :: Coil Pack Rust When Changing Spark Plugs
Oct 16, 2011
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.

2001 MK4 GTI VR6 put brand new coil pack, wires and plugs in the car because it was misfiring. Was fine for about a week than I got a clogged cat code and could feel the affects. I now have no cat, no resonator, and no muffler. The car is finally driving good and then the check engine light came back. It says only a misfire in Cylinder #3 and when accelerate hard to speed up my check engine light starts to blink until I stop accelerating hard. So my guess is the clogged cat caused that cylinder to misfire but I do not know the actual solution to this. My EVAP hose is semi-pinched and when u squeeze it you can almost kill the engine. The weirdest thing of all is this: driving normal I shift in between 2000 and 3000 RPM and once i get into 4th gear about 2000 RPM......my car starts shaking badly and i feel like my engine is going to fall out. I have searched and the only thing i can think of is a bad injector...

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"??

2004 passat 1.8t. How do I remove the coil packs on the top of the spark plugs, so I can repalce the plugs.
I unclipped the wire and unsure how to pull the coil pack off.
No bolts. can turn it and maybe pull, but doesn't budge and don't want to break.

1998 Ford Explorer. Coil pack isn't putting out spark to that cylinder. Would the next step be to replace the pack, or might I check something else 1st?

I have a 2002 prius that threw a spark plug and loosened the coil pack. The mechanic just reinstalled the plug and tightened the coil pack and said it was fine. Why it would throw a spark plug?? It was running fine, no warning lights, i just heard an unusual slight noise and opened the hood to check it out, and notice the loose coil pack over the first spark plug

I removed all the spark plug wires for testing/cleaning and install new spark plugs, but stupidly forgot to mark the wires where they came off at the Coil Pack. yes, Now I cannot find a diagram for the Driver's Side wire positions at the Coil Pack.
(The Passenger side wires are 1-2-3, starting from the front of the engine, simple enough); The Coil pack itself has numbers stamped on it, so I have the Passenger side done correctly.
But the Driver's Side wires are not in a Sequence of 4-5-6, instead they are 4-6-5 (or something like that), and I can't remember their positions at the Coil Pack. Looking for a drawing showing the Driver's side Wires as they connect to the Coil pack?
Example:
Front Driver's side plug wire connects to which coil pack position? (Front, Center, or Rear?)
Center Driver's side plug wire connects to which coil pack position? (F, C, or R?)
Rear Driver's side plug wire connects to which coil pack position? (F, C, or R?)

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?

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.

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.

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 was removing the coil packs on my car in preparation for the new ones coming in. The far right coil pack came out very easily and was about half as long as I expected. The other half of the coil pack was at the bottom of the spark plug well. I reported a misfire yesterday. As the mechanic would say "now there's your problem". removing the bottom half of a coil pack?

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.

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.

B5 Passat, it has the 2.8 and it has been having moments of shuttering so I did a scan and hit 3 engine falts, I did do a clear and rescan so these are new faults.
3 Faults Found:
17801 - Ignition Coil Power Output 1
P1393 - 35-00 - Electrical Malfunction
17802 - Ignition Coil Power Output 2
P1394 - 35-00 - Electrical Malfunction
17803 - Ignition Coil Power Output 3
P1395 - 35-10 - Electrical Malfunction - Intermittent
Right now my guess is the coil pack is going out or loose connection to the coil, this coil is roughly 8 months old so it kinda has me at a loss and hoping its not the coil.

I'm driving down the road yesterday, and going through a intersection, get through it i'm in 3rd gear, 20mph, and my car starts to misfire, so i am like crap coil pack, i changed them all with new plugs maybe 1000 miles ago. Well I slow down so i can turn around and head back to my place slowly a mile away. and it never happens again. Now the car had just had the complete exhaust replaced last week, and literally only 9 miles put on the car before this happened. I drove 35 miles to work today, and roughly 50 miles last night after this and it has not happened anymore. Am i doomed for coil pack failure again?
