2007 Suburban 1500 5.3l with Afm cylinder activation “feature”. A few months ago the engine started running rough, it had no power, had a misfire on cylinder four, the traction control and check engine lights came on. It also shifted really hard. Didn’t know what the problem was, checked fuel pressure, spark plugs, swapped coils, still had problem. Learned about Afm on the engine. Pulled intake plastic cover, VLOM plate, saw cylinder 4 full of gas. Learned about stuck lifters. Sharpened one side of the end of a long skinny bolt to a taper, stuck it down the oil hole under the VLOM plate for cylinder 4, tapped it with a hammer until the lifter popped opened and I heard a big whack when it released and the rod shot up. Followed YouTube video and cut the oil passage gaskets on the VLOM plate so it could no longer feed oil into the lifters to deactivate them, or allow pressure to build up which could also for the lifter to re-collapse. Found that after cutting the bottom half off a small socket, it fit perfectly under the pressure sensor to block the oil from feeding into the VLOM plate passages. Reinstalled everything. Engine ran great as it’s always in v8, but it would still try to deactivate and the rpm’s would drop which was annoying when driving on the highway. I’m not sure what happens in that case? Does it still fire the spark plugs on the deactivated cylinders, does it still inject fuel into those cylinders?? I bought and plugged in this deactivation device and it has been working perfectly for over 4000km so far. Engine no longer tries to go into 4 cylinder mode. Super happy with it, leave it plugged in all the time and hasn’t drained the battery, thank you!!

Works as advertised. The device does prevent the engine from going into 4 cylinder mode.My vehicle has about 500 miles on it with this device installed and the lifters no longer click at idle. I have noticed no significant drop in gas mileage in city driving but have yet to check highway mileage.Oddly enough, there is no mention in the instructions of the push button on the left face of the device. This is a latching push-on/push-off switch that disables the device. It appears that this switch also shuts off power to the circuitry thus preventing the device from drawing any current when the engine is off. This feature would ensure that the device wouldn’t drain the battery during long periods of inactivity.

Plug and play. Installed on my 2017 Yukon with the 6.2. Turns off the afm as described and full power. All cylinders used. Went on a long trip and didnt notice much for gas mileage but always had full power which it should have. City driving is great. Don’t have the jerking from the afm constantly coming on and better throttle response. I like it. It has auto shut off when not in use which is why I chose this one and for the price it works great.

Installed on 2018 Silverado 5.3L. Have had it in use for 24 hours and is as advertised. V8 100% off the time. Still need to record the MPG gain/loss with being full V8 all the time. So far averaging around 20, some highway but mostly country road driving.

Put on our 15' GMC with a 6.2L and its great. Can't believe the change in power and shifting. Wish we did this sooner.
