V4 scares me

[Jsdirt]

Well, we won't know for sure until the new trucks get a few years & miles on them - they're all nice when they're new (unless you were one of the unlucky ones to buy an '09 that burned 2 quarts of oil in 200 miles, right off the showroom floor).

 

My oil burning is completely unrelated to AFM - it's 100% piston rings. That's just half-assed manufacturing. You'd think after over 100 years of building internal combustion engines, they'd know how to keep crankcase oil OUT of the combustion chamber ...

Did I read where disconnecting a wire on the brake booster would keep it in V8? 

Did I also read where the electric vacuum pump can fail and create havoc?

would disconnecting that wire solve both problems without bad side effects elsewhere?

Vacuum pump is belt driven. Failure of it can destroy engine sometimes it has been reported . Have also read disconnect wire at brake booster disables AFM. Downside check engine light stays on they say.

I didn't notice better mpg with it enabled and then I found the posts on here about oil consumption and disabled it. haven't looked back and wont re-enable it unless I get rid of my current truck and the tuner will work on my next truck.

Is there a picture posted of what the plug looks like and it’s location ?

[pickmeup]

Have not seen a picture . All I read was it is a sensor located on the brake booster .

Interesting.

sounds like the OP has made up his mind before asking the question...i think the more appropriate question would have been, '(I) am thinking about getting a range...I've read plenty of reviews, but wanted to get more personal insight..."

 

just like anything else...millions of GM trucks are sold...and if there are a few thousand issues, you will absolutely be able to find people complaining on the internet.  (probably justifiably so)...but statistically, (not 'countless' articles, because they are countable) what % of vehicles have issues specifically related to AFM; from there anyone can say...well...for a .00025% chance I have one of those trucks, i'm gonna shut mine off...or whatever risk matrix each of us as individuals choose to use (for example, I have had 3 fords, all of which the transmission crapped out well before 100k miles...the newest was a 2004 Explorer, which probably doesn't have a single part in common with the new Fords, but guess what, I won't buy another ford)...

 

anyway...I had a '08 Silverado 100K miles, no issues whatsoever with the AFM, I now have a '16 with a little over 30k, and again, so far, no issues...

Thanks for the criticism, initially I’m interested in people’s opinions and experience with the Range, now the thread is leaning toward a free bypass method such as disconnecting the wire to the brake booster. If you have no help then I suggest you find a different thread.

hey, stop using all that logic. this is the internet. no place for that here.

 

seriously, I can't get over how many people read a forum and think every truck has a problem. GM sells around 1,000,000 trucks every year. Thats about 4-5 million of the current generation trucks on the road. of course there are a few hundred or even thousand with any given problem, and they all post on this forum. but having a 0.1% chance of anything going wrong is not worth getting all worried about. Every car from every manufacturer has the same odds of problems.

No vacuum pump on mine. As for disconnecting anything on a modern vehicle, there's going to be unintended consequences of that - anything from the MIL coming on, to ABS no longer working, and the light on (no go if you live where they inspect) for that.

You'd change your thought process if you worked on them for a living.

I get that its all about perception. But you fix a couple trucks a day. Do you not notice the 100 trucks you see on your drive home that are not in the shop? Are you also someone who goes on webMD when you have a cold and end up thinking you have a rare disease? just because something is possible does not make it probable. I try not to worry about such things in life. If my truck develops a problem, I'll deal with it then.

don't get butt hurt over a logical comment on the o'l interweb... you asked for opinions...

My '07 had AFM and towards the end (100k), would burn at least a quart per oil change.  Sometimes closer to 2.  I did go longer on my changes, but it still shouldn't be using oil.  It went through half a quart per change when it had well less than 50k on it.

 

But I feel good knowing I saved ounces of fuel over the 10 years and 100k miles I had it . . . 

 

My '17 hasn't burned any oil, but I'm at 5k miles.  I'm gonna give it some time before i judge!
