LOW IDLE RPMS

My 2020 Silverado 1500 5.3L V8 idles between 100-200 RPMs while in park and stopped at a light.  I think this is extremely low but when I called my dealer they said not to worry.  I thought 500-600 RPMs was normal.  What's the right answer?

I doubt it can maintain even running at such a low RPM. May be your tach. I’d get it checked out.

Maybe an obvious question, but is your auto/stop feature working/engaged? The tach's look kind of funky on the T1's where it drops down to the auto/off feature (hope my terminology is correct) when the engine shuts off when stopped.

I always turn my auto stop off when I start my truck, so I don't think it's that.  If the first line is 500 then that would be the answer.  I'll have to look next time I drive my truck, but aren't there 5 lines before 1000?  Mine idles between the first and second line which led me to believe that I'm idling at approx. 200 RPMs.  Can anyone confirm the first line is 500?

Where the needle rests and the first line is where it will be when in autostop. First line is 500rpm, each line is 100rpm. It shows more clearly when you look up between 1000-2000.

Quick math man lol, What's 500 + 100 five times, that's 1000.

Hey camGTP...no need to be a smarta%% as I just forgot that there are 5 lines up to 1000 vice 10.  But thanks for the math lesson.

Yea, first time I had a T1 (only one so far) for a loaner, it took a couple of double takes to figure out what was going on with the tach, was not a fan of it and the auto stop.

 

Keep asking questions, lots to learn about the new rolling computers.....

looks like mine is setting @500, could be an issue with the display is not showing the right RPM because I doubt the truck would run as low as 200

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
