I have a 2020 trail boss custom 4.3l. Probably a stupid question, but does anyone know if this has the cylinder deactivation? If so does it take it to 4 cylinders or 3?  Also is there a way to turn it off?

I’ll take “someone who shouldn’t be critiquing others about the English language” for $200, Alex.    Your posts are riddled with poor grammar, misspellings and the improper use of “your” vs “yo

The 4.3l is a great motor. You’ll love it. As for the other comment by Teddy Ruxpin.  Move along old man.

There are two current versions of the Gen V 4.3 known by the names LV1, non AFM and LV3 wit AFM. No pickup has been fitted with the LV1 yet. All GM pickups that have a 4.3 have AFM. There in may lay the confusion of the ignorant.

Wow, no need for the name calling!!  Just kidding,   thanks for explaining it to me.  1 more thing, do you think this is the reason my v6 sounds like a sewing machine? Because its running on 4 cylinders? or are these engines just noisy?

It idles on all six so any clicking and clacking at idle is a product of the direct injection system. Normal.


When driving under light load and it drops cylinders you may also notice a different sound and slight vibration.

1.) Your welcome

2.) I wasn't call you ignorant. I was calling  your source ignorant. Back up and reread my post. I think you will get it.

3.) That sewing machine sound is the high pressure pump humming away. 

 

That out of the way the three musketeers (TNTSilverado, OnTheReal & f8lvnm) who offer no help seem to have problems with English contextually. Best responce....name calling. :crackup:

 

PS I see a typo in my first post which I corrected.

Your posts are riddled with poor grammar, misspellings and the improper use of “your” vs “you’re”. Almost unreadable at times.

I had a 4.3 in my fleet, it was rock solid, excellent runner from one port to the other. Burned just as much fuel as the 5.3’s and the 6.2’s, was the #1 choice for inner city driving by my employees. The workers also loved its reliability, zero breakdowns, wish I could’ve said the same for the diesels and 5.3’s.

Unless you’re towing it’s the great little engine that could.

Was that motor the Ecotec3 Gen 5 or an earlier 'iron' 4.3? My father has run those iron motors to over 3/4 million miles.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, they can remotely disable the device. B) Make sure it's paid off. If they still owe money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.

      My point was: If what you are doing works, keep doing it:   But, I will have a talk with AI to make sure their info is more accurate going forward.
