What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Sparksalot]

Shit man last time I did mine at least half of the wires broke off like that inside of the heat shield sleeve things. Do you have those? I don't see them in the pics. I used dielectric grease on the new wires hoping that would keep them from welding themselves to the fkn plugs again.

I used special spark plug wire pliers and long reach pliers and they still fkn broke off. And what I mean is when they break off the boot comes off but the metal clip that snaps onto the ***** on the plug rips out of the wire and stays on the plug tip.

I don’t have a pair of the boot pliers. I know what they are, but don’t think I could get down in there with them anyway.

Yes, I had slipped them off as the wires came out.

DBW TB doesn't have an IAC valve.

Good to know! Was planning to finally clean my TB (1st time in 13 years! Haha) and was going to track down the IAC valve to clean also.

My apologies for misinformation JustFishing! You’d think the older I get the wiser I’d get by not spreading info that I simply assumed.

The easiest way for me to pull the ds #8 and #6 plugs and wires out--without breaking them--was to actually lay on top of the motor, my feet hanging over the grill--it put me at the perfect angle to take everything off without breaking anything.

That’s what this sheet is all about. Laying on top the Hoe.

I'm afraid to break something laying my fat ass up on the motor LOL.

And #8.

Is that the oil dipstick that bit ya there? I pull mine off going after that plug back there.

That’s why I stuck to the fenders. I’m also a bit short, so it helps doing this.

Actually the much and crap on the heat sheild fir the AC filter/dryer.

Even side, over an hour. Odd side, 10 minutes.

Took apart the rear taillights, cleaned the sockets and replaced some burned out bulbs. Fixed a rattle in the dash (resulting from careless assembly / disassembly by previous techs).

Found a gizmo under the dash the Feds use to automatically record odometer readings at the gas pumps. Apparently when you're spending other people's money no convenience is out of bounds. Removed it.

Looks like I'll be replacing the big electrical junction block that mounts behind the parking brake. Some careless butcher of a tech broke all the mounting tabs on it.

I found out years ago these long curved pliers come real handy for pulling plug wires and the metal shroud, harbor freight win
they have a pretty good grip, came in handy many many times, I think this set is about 20 years old

Those would be handy!

The ones I grew up with had nylon jaws. The idea being to not destroy the wire getting it off.

I usually no longer trust the wires once they have been pulled off unless they are not very old that core material rips very easy anytime I have pulled them off even by hand I am not sure if I ripped one or not, it might stem from me just having bad luck with plugs and wires so many times I have done them and then a week later "misfire"

Yup- it's all-in-one now. Instead of the PCM controlling a separate electronic valve to adjust the amount of air needed for idle, it just controls the main throttle blade since it's electronic.

Do you always dress like a ghost or just when you work on your cars?

I usually no longer trust the wires once they have been pulled off unless they are not very old that core material rips very easy anytime I have pulled them off even by hand I am not sure if I ripped one or not, it might stem from me just having bad luck with plugs and wires so many times I have done them and then a week later "misfire"

I pop the end off the coils then spin the plug end of the wire around a few times. Then slowly pull out on it as I work the end in a circular motion. Sometimes I have to grab the heat shield with some long needle-nosed pliers and wiggle and pull it by that.

Haha! That’s exactly what I was thinking!

That’s what I did after the first two.

I agree. With these I have no idea how old the plugs and wires are. Possibly original?? Plugs were 41-110, and wires were Delco 5146.
