2014 Sierra 5 3L Misfire #4

[@terryraygould9346]

After spending a ridiculous amount of time chasing a continuous problem with plugs fouling on #1 on my 5.3L Silverado, I finally installed a Range Tech module to lock out the AFM shutting down 4 cylinders. 6 months later and no fouling or misfires I pulled #1 to check. No fouling. No problem. UGH. Thank you Chevy for owning up to an obvious problem with your ^%$%^$$$AFM system. Can you imagine all the recalls if they actually admitted that their AFM system was causing premature engine problems, code problems and failure to pass inspections. Yeah right.

[@nv1493]

And the AFM debacle continues. Many miles ago I plugged in a Range Technologies AFM module (OBD port). Keeps it on all 8 cylinders all the time. 2011 5.3 @115k miles, so far so good.

[@ronaldlewis4032]

I going to order me the Range Technology Monday! Thanks

[@mrc5485]

Iv had my range module for a year now on a 18 sierra z71. Best purchase ever highly recommended to anyone who wants to keep it in V8 mode

[@edlauren9434]

Thank you man for this video!

That’s the one I’m having issues with. I’ll be working on it this weekend

[@jaydenimpton6798]

Just learned a transmission shop can delete the cylinder deactivation in the computer. Haven’t done it yet, saving some money to have it done

Hey I have a 6.2L GMC Yukon Denali XL but mine does not move in and out, the rocker arm has a little play side ways and it’s on some of the cylinders on Bank 1

[@chillbro8811]

Oh boy I'm having second thoughts about buy a used 2014 5.3 Sierra now 🤦🏾‍♂️

[@fsteddie98]

It’s a Gamble for sure. If possible buy Insurance with the used engine

[@joonienyc]

Hey i have 2015 suburban and it has code p0324 coming up when i accelerated on highway about 60mph, engine started to have ticking sound, i don't know whichside of the engine coming from, but i know if i slower down my speed, the sound go away …, but the code stays on P0324 knock systems error, could it be the same issue as in the video?

[@ronaldlewis4032]

Is this still on a 2016 2500 Chevy??

[@spelunkerd]

Governments forced manufacturers to make their vehicles more fuel efficient. What they didn't enforce is a way to show those same vehicles are durable. Manufacturers don't complain, they get to make more new vehicles, and their main competition, old cars, are gone. In the end, overall environmental costs rise because cars don't last as long. It's a win for manufacturers, an overall loss to the environment and consumers.

This needs to be on a bumper sticker. Or at least taught in schools

[@MrJamesgrate]

How long did it take you to complete the job, I had a service engine code once stating the same problem and same cylinder, I took it to the dealer and left it, while I went to work, the dealership notified me that the truck was fine, it just had a loose spark plug wire, it seems strange that it took them all day to repair the rough idle issue I had, and since I just discovered your video, I wonder if my dealership had to perform the same diagnoses and repair as you did? Great video!!!!!!!

[@fsteddie98]

The job takes about 6 - 8 hours to complete. If your resurfacing the head which I didn't it will take longer because you would have to wait for the machine shop to finish before you can put it back together.. thanks for your feedback

[@MrJamesgrate]

I appreciate your quick response, and insight to what a job like this would involve, so maybe the dealership was being honest when they told me the spark plug wire worked loose. Again great video, and thanks for answering my question!!!!

[@Lethalinject101]

What does a job like this usually run price wise? I’m pretty sure I had this happen to me on the way to work today, getting on the freeway under acceleration not wide open and CEL starts flashing, rpms are jerky/sluggish just below 3k like they don’t want to climb. Idk I’ll be in the shop tomorrow this sucks though.

[@fsteddie98]

Labor for replacement of one or all active lifers on one bank is about 12 hours it can run you about $1200 to $1500 plus parts

I have a p0306 with misfire on a 2015 Yukon flex fuel system and eco tech but my Yukon has white smoke coming out of the exhaust any idea what it could be?

[@worstnightmare9772]

Ya sell it for 5,000 firm and get a K1500

[@fsteddie98]

White smoke usually means burning Coolant. Is the misfire constant? Does it misfire more at first start up?

[@ej1robb]

@@fsteddie98 yes it’s constant it was worse but I had changed all the spark plugs, wires, & coil on the 6th cylinder. The misfire isn’t that bad but still there. Didn’t smoke until I changed all those parts

[@fsteddie98]

@@ej1robb sounds like what u have left is a Mechanical issue like compression or Fuel injector at this point I would have to hook up a scan tool to run an injection test and also check compression.

Will you use up grade lifters and trays! I got one that's jerked since it was new! Sometimes I just air it out then runs okay for awhile I guess I need to just speed every day! Lol

do the rocker arms on #4 cylinder move whit the eng running at idle? if they do then i would say its not a lifter issue. I would check compression on that bank it should be about the same reading + or - 50psi to 80 psi
