  1. Oh, okay. Just curious what product the dealer installed on your 2017 for your hard earned $1000. Did they give you any information about it? I am intrigued about any type of corrosion prevention as it is a never ending battle here.
  2. Just curious why? Aside from a couple weeks of dripping in the hot weather.
  3. Mine is at the dealership right now for a minor vibration issue and some recalls. Regarding the vibration, I did ask the service advisor about the tsb regarding the transmission fluid & a new replacement fluid that is available. I told them to keep the truck as long as they wanted and to rack on as many miles they wanted. The shop foreman took my truck home after work a few nights ago. He did confirm the vibration I am feeling and reached out to a technical advisor from GM. I was told GM has directed them to change the engine mounts. I will update this post when I get the truck back home. I have an 8 speed 6.2 if it makes any difference. Maybe there is a new bulletin regarding updated engine mounts.
  4. It is interesting when your revolutions increase the oil pressure gauge decreases, almost in tandem together. I wonder if there is a shared ground connection somewhere that is starting to deteriorate. Hopefully someone on here will have an electrical diagram to see if it is a path worth exploring. Checking oil pressure with a mechanical gauge is the best advise you have been given so far. I assume your oil level is at the correct level.
  5. I have had great luck with Ctek's line of battery tenders. I am in the same boat as you; the truck can go months without being used.
  6. Can you humor me and idle it for 20-30 minutes in the driveway and watch for fluctuating rpm's like shown in your video.
  7. Would you be able to start the truck from cold and let it idle for 20 or 30 minutes to see if the fluctuating idol condition happens? Monitor what the rpm's are doing during warm up. I assume you are using premium fuel? If it behaves fine in the driveway, I wonder if there could be a transmission issue.
  8. If you start the truck when it is stone cold, how long will it idle until the rpm's start to go erratic? Does the truck have erratic rpm's when you first start it? I don't think my limited knowledge is going to help, but maybe if we banter back and forth enough, someone else will have a eureka moment. I wouldn't think the ecm would "relearn" the crank position. I don't think it has any outside influences; it is what it is. Can someone confirm I am need feeding Mr. Jameson a line?
  9. Mass air flow sensor? I don't know how to function test it, maybe someone here does. I'm sure you are tired of throwing parts at it. In your video, the idle rpm's are erratic. is this actually happening, or is this you touching the throttle? Noticed your check engine light is on; do you know what it is? I want to throw a dart in the dark and say a crappy ground connection somewhere, but you indicated the main battery cables were already replaced.
  10. That seems a little premature. Avoiding big crowds, unnecessary social outings & washings hands frequently & PROPERLY seems like the only rational things to do right now. Unsubscribe to the panic, let common sense prevail. Take some time off if you can, watch the boob tube & read some books. Perspective is important; around 300,000 Americans die prematurely each year due to obesity. Not hardly a whisper about that sad statistic.
  11. Buy the kit again from the same supplier. Hopefully they send the right one. Put all the wrong stuff back in the box and return. Dishonest? I am conflicted.
  12. My good pal got into an 80 car pile up during white out conditions. 2016 ram 1/2 ton diesel (beautiful truck by the way) 7 weeks ago. Body shop is still waiting for some OEM parts to become available. My mother backed her new Toyota RAV 4 into a post. Damage was minimal, but parts were 5 weeks back-ordered. Not just a GM problem; they all suck.
  13. NAFTA. Chicago school economics. Globalization. None of the above was for the benefit of the people or society. Fellow human beings at each others throats < race to the bottom Everyone take a step back; whom is really winning this battle? Why is North America in its current state? Educate yourselves (read some books); my eyes have certainly been opened up this past year. The question should not be "why is their pay package so generous?" rather "why isn't mine?" For the record, I have very strong views favoring certain aspects of socialism. Have a pleasant evening all Cheers, Brendan
  14. The dealership call and said 'Hey, we have some great deals on right now, why don't you come in and take a look". I have a rubber arm, so I said "OK".
  15. Just a shot in the dark. Maybe give Moog suspension a call to see if you can get some spring specification details. I did what you are describing in my Lincoln Town Car. Just curious, is there a truck you have memory of with a softer ride that you liked? A spring rate that you might like may not be listed for your truck. I my case with the Town Car, springs from a 1982 Oldsmobile Brougham were a prefect fit for my 1995 for a nice soft ride. Go figure. There was a slight drop in ride height.
