    AFM DFM Conundrum

    This is the path I'm on right now. I have the plug that keeps it from shutting down cylinders and it's working fine. Now I'm working on my plan for the mechanical parts replacement. Have a ace in the hole, a 30+ year chevy mechanic that can help answer questions if not wrench alongside me...

    AFM DFM Conundrum

    Great info! I didn't think that deep about the other maintenance parts but those are great ideas. I'll have to dig deep and see if I can shell out for some headers and exhaust at that time too...LOL. I think I can convince my buddy's a work to split a tuner, we have plenty of cars that could...

    Elusive oil leak

    Sorry, I don't know what you mean by 'rear cover' - are you referring to the rear side of the valley cover? Just want to make sure I'm understanding this correctly. Thanks!

    AFM DFM Conundrum

    Hmm, well it I have to, I have to. Thanks for the references on that. I would love to hear from someone that did the delete themselves. How long did it take and where there any parts not included in the kits that you found you needed? Or are there any parts that would be good to replace...

    Elusive oil leak

    Any update on this? I have an oil leak I'm looking for and I'm curious if any of this helped. I never see oil on the driveway and it seems that it only leaks when the trick ('16 Tahoe LTZ) is running/driving. It's only been an issue for the past few months but I've gotten a "Low Oil" warning...

    AFM DFM Conundrum

    I bought and installed the AFM disabler almost a year ago. Found this one on Amazon (https://a.co/d/05DPjgno). It has a very small "footprint" so it doesn't stick out and get caught on things like I think other might. I got this because I was starting to have lifter issues and since then I've...

    Driving in M5 to disable the AFM, transmission question

    I have a '16 Tahoe with 165k on it and I've been using the L5 method for about 2 months now. No issues at all, in fact I've seen an increase in MPG - slightly. I'm about to get one of the disablers so I don't have to remember to use L5 each time I shift into drive. Plus, when I go on a longer...

    AFM

    How are those AFM disablers holding up? I'm thinking about plugging one in while I save for the full delete kit. I have a friend who's been a GM mechanic for a LONG time and I'm hoping to get his help when the time comes. I also have an extended warranty until July 2026 so I'm thinking I'll...

    Grinding Noise At Cold Start

    That's the air pump for sure. Mine had that same sound when I bought it and it took a while to figure out what it was. Replacement was quick and easy. I didn't the rear shocks at the same time. Unfortunately that didn't fix the rough ride issues I'm having but it did make the pump quiet...

    2017 Yukon Denali Rough Ride

    I have a '16 Tahoe LTZ that feels the same as what everyone is saying. I bought it last July, replaced the rear shocks with Dorman magride's, replaced the air pump and when that didn't help I replaced the fronts with TRQ active magride's as well. The ride still isn't right. I know from...
