My fathers 2004 Sierra ECSB 4.8L Auto, has a skip when you let the motor RPM drop and lug a little. This happens if the truck is in 3rd or OD, but if you floor it, there is no skip. It only happens when it lugs. We replaced the plugs and wires, but no change. The CEL is not on. We tried new gas, fuel injection cleaner and dry gas, no change.

Any thoughts?

  2017 Sierra 1500 SLT I read that there’s a bolt on the battery brace that sometimes gets loose. I checked all the bolts around there that I could, and all were tight. This sounds more like it’s under the dash, maybe closer to the driver footwell. Anyone else have this problem, or know a possible cause? https://imgur.com/a/kaQRZZH

  Morning here- I have a 2013 GMC Sierra 1500-5.3 L engine (low mileage -two owner)--I'm retired now-so I don't drive as much--anyway-just had the oil /filter changed-I have always used Amsoil Synthetic and NAPA gold oil (#7045) filters-now i read that GM has changed the oil filter requirments for these engines- and they (GM) recommends/ want to go w/ a different filter w/ more psi rating on the relief valve (in the filter) to open like 22 psi. The above featured one I mentioned shows 12-15 PSI--which doesn't kmeet these new specs.. Wow-stuff is like getting more/more technical all the time. I think it looks like trying to avoid these sticky lifter problems. Any thoughts or recommendations here? I'm kinda confused-- Thank you- glenn

  ///// I went ahead and bought/plugged in the new Boost brand dongle thing last week. Haven't driven it much yet-but seemed a little smoother/quicker maybe in stop and go traffic. What I did like about this brand was the reviews and made in USA> (hopefully).

  Headlights look aftermarket. Now replace the grill and maybe do something with front bumper.
