I wouldn't be happy with that, you shouldn't be paying anything more than the difference in MSRP, on a trade assist, the rebates don't matter GM is basically making you a new truck and taking your old one.

I agree that I should not have paid anymore than the difference. However, I'd rather pay the extra $400 and change on one of the rebates and call it a day. The way I see it, I haven't paid for gas or even made a payment on the truck and I have it over a month. It wasn't worth it to keep fighting at that point. Still feel I got an overall good deal and I'm happy with the truck I'm getting.

Thats what I'm saying though, the rebates dont make any difference what so ever, the only thing you are required to do is pay the difference in MSRP which would be your upgraded truck. They also have to move all of your accessories over or reimburse you for them so they aren't doing you any favors lol.

I ended up paying $179 over MSRP difference. But, because I bought the truck on Oct. 2nd, I ended up qualifying for a $700.00 Costco (warehouse store) gift card promotion. I think things workout out pretty well.

I would get the check engine light problem address before worrying about the rough idle. They maybe related as whatever emission device tripped the check engine light, may have been defective for so many start cycles before tripping the CEL and maybe the cause of the rough idle.

I'd say thats a pretty rough idle !

I had the shims put on the engine mounts earlier this week. They didn't seem to help the rough idle.

Has anybody gotten this fixed yet w/o trading the truck? Mine shudders pretty bad still, almost feels like a misfire but no CEL or codes. Doesn't fdo it that bad once warmed up to 210. If you open the hood, you can visibly see it shaking through.

the only thing that helped eliminate my idle vibration was having Blackbear tuning raise my idle RPM from 500 to 600. Not my truck idles smooth as glass.

Good deal, I have a diablo and I know I can adjust idle rpms as well, maybe I will give that a shot. It isnt bad once warmed up, but while its on its way to 210 deg it sometimes shudders pretty bad a feels like its going to conch out. I will also use the diablo to check to see if there are any stored codes that didn't trigger the CEL.

I had them do the same thing with my tune. 500 RPM is too low for a V8 to idle smoothly IMO. 600 is minimum.

The idle RPM gradually drops as it reaches 210 degrees, that is why you'll only feel it when its 100% warmed up. I'm convinced its to help with emission checks as Park and Neutral are both set at 600RPM.

IDK about the 8's but with my 6, they adjusted the timing, the cross pipe into the cat, and that helped. it didnt eliminate it 100%, but it helped

      2018 Sierra 1500 Transfer Case Leak

      By Ryanwehr14 · Posted

      A while back, my truck (2018 GMC Sierra 1500 5.3) went in for an o2 sensor and routine service. The tech identified that my rear output seal on my transfer case was leaking, and recommended I have them replace it. At the time I didn't think anything of it, and had them do the repair. Less than a month later, I noticed that the recently repaired seal was leaking again. I called the shop that did the repair and they warrantied the repair and replaced the same seal again. A few months later, I noticed that once again the same seal leak had come back. It wasn't a great time to bring it in and I ended up just living with it for 6 months or so, noticing small (smaller than a baseball) size oil stains below the truck when it would sit for a while, as well as oil spray on the frame (to the point where it actually took the underbody coating off in that one spot). Finally got around to brining it in again, but this time I took it to a dealership service center since I am in a different part of the state for school. They identified the same output seal leaks and recommended they replace them. They also said there was no scoring on the inside of the transfer case, so it didn't need to be replaced. They chalked up the original repair failures to non oem seals and a job that wasn't done correctly. Now they called and said the seals are holding after driving/sitting for a while, but they found a very small leak in the middle, that they recommended they seal with some kind of silicone/jb weld (not sure what they are using). I haven't picked up the truck yet, but I have been reluctant about this whole repair process because I feel like they are just fixing the same thing that keeps coming back, and I am concerned there could be another root cause for the seal failing. Has anybody else experienced anything like this, or have any ideas on other things that could be the root cause?

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.
