I have already bought all the lifters and then I found this video!!!!!

I have a 2012 Chevy Silverado 1500 5.3L. I had new catalytic converters, muffler, pipes and tips put on and now I'm noticing something I didn't notice before, an exhaust sound changes when the AFM switches from 8 to 4 cylinders. Plus, I'm seeing a push of smoke after pulling out from a stop sign or red light intermittently. I replaced both valve cover with the updated version, so I know it's not that. Well, that's 2 questions, I guess. Is the change in exhaust sound normal when the AFM switches and what could be causing the intermittent puff of smoke? I've got a 3rd question for you..... Is it normal for the AFM to be switching at low speeds, like going through town at 25mph?

What if I’m having a misfire on all 4 AFM cylinders?

My 09 avalanche is having a misfire and a good amount of white smoke when reving it i hope this works if not its okay

AFM needs about 27 psi to activate. I have low oil pressure (probably the oil pan relief valve is bad) and rarely makes it to 27psi on the the highway so it never activates.

Unplugged on my 09 envoy and no check engine light came on???

hello what happens if you use a cheap scan tool to deactivate AFM? will it fix this issue also or not really?

My 2015 Yukon Denali is currently in the shop having all the lifters replaced. I have one of those Range AFM Disabler that I'm going to use when I get my vehicle back. What is that test set? Are they expensive? I would love to look at the codes and alarms in my system.

Sorry if this a dumb question once the lifter is not collapsed can u just plug it bk in and work ?

Praise GOD IN JESUS Thank YOU

Have a 2011 5.3 Silverado. I tried an AFM DISABLER, it worked sort of for a week then back to shuddering. I'm going to try this now.

Great filming, good fun, good times!

does this work for 2011 gmc sierra?

I have a question. I have a 2008 Suburban 5.3 and I want to prevent the problems that arise from the AFM & DOD. If I replace the valve cover with the new baffle and then do the tune to the ECM would that prevent the engine light from coming on? Thanks for your hard making this video...

Didn’t try it yet but regardless, excellent information buddy. Thanks

So i am throwing the p9306/300 and it specifically ssys its cylinder 6 misfire. Changed the spark plugs my next go to is tbd coils and wires im reslky thinking that is the issue with the behaviir of the truck. Does this hack apply to the cylinder 6 misfire also?

I'm dropping everything and running to try this now

Someone told me it was a cam. Please say it’s not true

May 5th 10:00 pm do u have to clear the codes. I unplugged mine on a 2008 Silverado and it didn’t change anything. My code is misfire on cyl 7. Have to undo battery or anything like that

Well done sir! I am looking at buying a 2006 Envoy Denali . Is their a definitive way to tell if I have DOD or AFM on the 5.3L? I have searched the net , forums & found yours on YT. (But with varying answers) Is it in the VIN#,?Or Tell by the valley plate? the owners manual does not even mention it. they say they get worst with age.If it was newer I would use your technique . But they say at the age of the SUV its not a question if its when. take care & best regards.

Will this hack work on a 2015 Silverado 5.3

My 2022 suburban has misafire on cylinders 3 Change 16 lifter camshaft spark plug ignition coil injector and still the same Tak it to the dealer it been 2 weeks and they didn’t figure out the problem

The only thing that sucks is in my state your vehicle won’t pass inspection with the check engine light on. There are only 2 counties in the entire state that don’t require it.

Well! This one didn’t change anything for my P0307 Cylinder 7 Misfire.

i have misfire #6 ...no compression on that cylinder....didnt worked for me :(

It didn’t worked on my 2007 suburban with the 5.3 vortec engine

How about the 2015 gmc 5.3

Did you have to unstuck the lifter first

I would have thought that even though you were able to disable the AFM, that the lifter would have still been stuck. Apparently, it was able to unstuck itself after you disabled AFM. I just ordered a Range module to disable my AFM, so hopefully, I'll avoid the stuck lifter problem and not have a check engine light staring me in the face. The issue I could see with having your check engine light on after your fix, is that if something else were to go wrong with the engine you wouldn't know it, since your check engine light is already on.

Will this work on a 2014 silverador

I used the range obs AFM delete. About $200 on Amazon

Was your misfire just random shaking at a red light? No issues under load.

There are better ways to disable AFM/DOD with custom ECM programming with HP Tuners. There are also devices you plug into the ALDL plug that will disable the AFM/DOD. I prefer the custom ECM programming. And disabling AFM/DOD will not always restore a collapsed lifter. In fact I have never seen it restore a collapsed lifter with only disabling the system. I have heard of a procedure where you pull the valve cover and rocker arm and pushrod and fit a long screwdriver down the pushrod hole and whack thr top of the lifter to unstick it. But if you keep it in 8 cyl mode where the lifters never collapse to begin with there is less chance of having a DOD lifter failure. The problem with having a SES light on all the time is if you have a different code set you are apt to not know it because you think it is just on the the brake booster code. Also having a code set will disable remote start if equipped.

Thank the EPA

what disd you use to remove it?

So I tried this and it didn't help my issue now my service brakes soon light is staying on. :/

Another simple fix is on your gear selector, switching it to M5. It will keep you in v8 mode all of the time without much compromise, the only annoying thing about it is having to do it every time you drive the vehicle.

Afm disabler 2010 sierra wont work

Tow/Haul button will also keep it full v-8, only drawback is remote start will NOT work while the check engine light is on, not a big deal though if you don't use it much.

Unreal! Was gearing up ready to order lifters etc etc etc. 👍🏼

My 13 z71 on #1 fouls that plug every 5k miles hopefully this will solve it

I have same problem but my suburban is 2003. The booster sensor isn’t there

Im getting ready to try it,doing an oil change first,if it works ill leave a comment,if it doesnt,,ill still leave a comment and unsubscribe

Deleted AFM program. wire wheeled all exterior grounds. including one under dash cover. (costs nothing) started back up with 5-30 Amsoil signature /3500 max oil change. Using 5x detergent gas. Flawless performance. More pep. shifts stronger. 1.5 MPG more. But most important: no more codes on dash ! Stock except for MSD copper core plug wires. 2014 Silverado 4.3 V-6, 83K.

"Range" makds a device - AFM disabler can - can be had for about $200, it will do the same thing. Plugs into the obd2 port and disables the AFM without any codes being thrown ❤

respect. thank you

Hi! My 2012 was giving a misfire code as well. I change the spark plugs thinking that will fix it. Now when I drive it kind of rattles or feels like it wants to stop. I don’t have an engine light on and the oils and temp are normal

i have a 2010 chevy tahoe hybrid, where is this AFM sensor to disconnect it?

If anyone wants another way to disable this when your vehicle goes to dod and drops down to 4 cylinder mode and if your vehicle is equipped with manual transmission mode go a head and drop to 5th gear it will automatically send a code to the computer and will never goninto 4 cylinder mode and really it doesn’t change much in regards to fuel economy and it won’t allow the engine light to come on hopefully this helps

Will it work 2002 Silverado
