First major tuneup on my 98 Ws6
#21
Got the plugs done today, the first 7 took me about 2 hours total, and the last one (#8) took me an hour itself. It's a long story. But now i'm just waiting for my MSD wires to come in the mail and then that part of the tuneup is done. Gah I wanna drive it soo bad... anyone know how to clean the connection on the coil where the plug wire goes in?

Yeah for the wires I've read that you want to put some dielectric grease for the connections on the wires.
For cleaning I'd assume just using a slightly wet rag and using that elbow grease
Your further then me now. I've been waiting for these specific bolts to come in so I can't mount my coils back yet :\

I meant like the inside of the connection on the coil. I may just pull them off and use a q tip with rubbing alcohol or something in there? They may be fine to just leave alone but I want to be very thorough with the job.
I will be cleaning the outsides of the coils with simple green or something of that sort so that its nice and clean and then i'll be putting dielectric grease all over everything. I'm hoping that the plugs, dielectric grease, and new plug wires solve my misfire issues lol. I somewhat regret putting the delco's in the car already though...

I have never cleaned the inside of the coil connections. But I've never seen a need to, as the wires have always come out with clean prongs and a good boot seal around the coil. There shouldn't be any dirt or corrosion inside that connection unless the boot was not sealing well.
There is nothing wrong with the AC Delco iridiums. I put them in my '02 this last summer, and the engine runs great with them. I have NGK TR55s in my '98 right now, and they don't seem any better or worse (but they won't last as long with the copper tip).

I wanted the Delco's because i'm adamant about putting American stuff on my car but I found that seemingly everyone is using the NGK's, as you yourself are. I found that the plugs that were on my car already were the NGK TR5gp. They were black on the tips but I have no idea how else to read them.
But I ran into the dilemma of my iridiums and their gapping. I ended up having to leave them gapped at .040 because there are so many people saying you can't gap them because of the delicate tip. Since the install of these plugs wasn't that strenuous for me, I think i'll leave these in for a year and then change to the TR55- something that is already gapped at the preferred range i've read which is .050-.060, or something that CAN be gapped rather than having to stick with a .040, which may be okay but still. Maybe i'm a little bit **** but....

I don't really see an issue with the smaller gap. This plug was designed to be used at that smaller gap, and is indicated by GM for this engine to be used at that smaller gap. Like I mentioned above, I put these in my '02 last summer, they replaced the original factory platinum plugs that were still in the engine. I have seen no downside at all from the smaller gap on these plugs.
Well then, I don't feel so bad about it anymore now that you say that. It just felt weird to me to go against factory specifications, but if the gap matters based on the PLUG just as much as it matters based on the ENGINE, that makes sense. I've never used iridium plugs before so I didn't realize all of this until now. Thanks for the information and feedback RPM

The more time you're waitin for the bolts though the more time to clean and detail other things I guess haha!

And yeah, I've been cleaning everything I can for the most part, but since its been 7-9 degrees these last couple nights I've been staying inside haha. I need to get a garage heater sometime.... :o

Hopefully it does! - I've seen posts where it has fixed the misfires people have been experiencing, so that'd be neat if it did

Yeah that's freezing I don't blame you for staying inside. I'm spoiled and get to use my dad's heated garage, but I don't always get to have my car in the garage which is why i'm taking major advantage of it right now

I sure hope it does. My friend has a really expensive scanner and claims that the misfire was between the plugs/plug wires, because his scanner said the coils were functioning fine. So those two things, with a sealed connection, should solve the misfire I hope.

Yeah, same here, during the winter I can have my car in my parent's garage-but any other time my bird is in the driveway :c

"A new spark plug has been released for use in the above vehicles. The new spark plug has an Iridium tip instead of the current Platinum tip. Due to the different tip design, the gap of the spark plug has also changed. The new spark plug, ACDelco Part Number 41-985 (12571164), is gapped to 1.01mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed to the gap required with the Platinum plug, or damage to the spark plug may result"
Hope that helps. And again, I put these same plugs in mine with the Delco specified .040" gap and have had no issues at all after doing so.
PS. Don't worry about the different part number. GM changed that number several years ago, but it's the same plug.

My very first time, it took 2 hours, and that as with an hour of having to run into town, buy new plug wires since I broke 3 of them trying to get them off and had to replace all plugs and wires at that point........
Total time under the hood the very first time including wires..... 1 hour.....
Dunno why it takes you guys so long to get this done lol.
On that note, I can usually get them all done in about 35 minutes now even if I have to do wires too..

WOW........the very first time I ever changed the plugs on a 4th gen, I called my dad because I see all the people on here talking about how it took 3 hours or 4 hours or 2 hours.....

If it hasn't been done yet look into changing out your rear end oil ( very easy )
You can also change out your Transmission fluid as well. My GM service brochure says it never has to be change but i would change it. My car is a 01 it could have 12 years+ old fluid in there.
RPM what do you think about changing the transmission fluid?

For the T56 listed in your sig? I don't believe there is any factory recommended change interval for this. But I am not an M6 expert. Either way, this fluid is under much less stress than fluid in an auto trans, so it would not need to be changed as often.
