Oh, I read it through but overall it sounds like the 4.2 is being a bit dramatic and should just calm down and stop being so extra 😂😁🤣

Um, yeah, I know what it is, but why is it important for the 4.2 engine spark plug particularly?

What exactly does "Iridium" mean in the grand scheme of spark plugs anyway?

No no, I didn't mean buying counterfeit products didn't matter; you have no clue what they are at all. Just that maybe some of the other legit brands might be OK to use instead of AC Delco since half time you're not even getting the real thing...

Believe me, I've had SO much experience with wheel bearings that I think I would know the sound if I was in the morgue... So I don't think it's that. I called it a rumbling but you could also call it a kind of vibration aswell when you hit like a bit above 40mph... Thankfully it doesn't seem...

Keep seeing stuff about these counterfeit products. I wonder sometimes if it even matters... I see stuff on Amazon at good prices that are aftermarket brands with great reviews from buyers. Add to that the prices at my local parts store for OEM Ac Delco parts are OMG expensive... x6...🤯

At higher speeds it did seem to stop for a second a couple times I hit the brake, but it was kinda hard to be sure at lower speeds...

Hummm... Is that, um, a really bad thing? Does it mean anything for the life of the transmission?

Since stations switched to winter blend petrol a few weeks ago, my 07 does a little rumbling when you get between approximately 40-50mph...Not anything serious but just something new. The throttle body has been cleaned as has the MAF. No other recent maintenance... 210,000 Kilometers on the...

New switch wasn't the problem but for 15 bucks who cares....Anyway, I managed to find a new TC encoder motor locally and it fixed the problem. Everything is working great again. Cheers!

Thank you. Gonna install the new switch before buying anything, give it a couple days and see what happens... I hope that's the end of it...

For the purpose of buying a replacement TC motor, most sites offer several options... NP8 with 7 pin plug is what I need with a 2007 TB LT...? I think the other options are for the trucks with AWD?... I know the Rainer shows different results than the Trailblazer and Envoy AFAIK... I'm just...

An 07 Trailblazer LT 4x4 system is an NP8?

I have a switch ordered. Getting to a place that can read 4x4 codes properly requires a day off and a tank of gas. That's why I like to hear others thoughts and experiences.

Thanks everyone for the replies. Today I started up as usual without issue. I drive for 20+ minutes, park and shutdown. About 30 minutes later I startup again and boom the 4x4 service light is on again and NO lights are illuminated on the 4x4 switch at all. I shut the truck off and flick the...
