Ok I'm new here. Got a 2000 Silverado 5.3 ls ext can. 3.73 gears 285/75 tires. Flowmaster super 10 dual out.

Getting terrible mpg like 8-9mpg and I don't feel like I have all my power and my truck is no were what I thought it would sound like with the exhaust set up.

 

Also did led swap on gauges but wanted to do the rest of the dash anyone have any info on doing that?

 

I do pull lean code both banks.

Your tires being bigger than stock are also going to throw off your gas mileage numbers. As far as lean codes, have you check fuel pressure?

Ok I'll do that for sure.

Also I had a squealing noise took the belt off idler pully didn't spin freely replaced that with new belt it went away.

Till today it started a very slight squeal.

 

Also my volt gauge runs like 16-17 volts. Alternator spun. Idk how free its supposed to spin tho.

Should spin freely no matter what. I get a volt meter to double check the output voltage. I've learned to not fully trust the gauges in my truck, I use them merely as references.

I just don't know if its supposed to spin as free as a idler pulley or if its supposed to have a little resistant.

 

I had the test ran from advanced and the alternator checked good but my battery was running slightly low on cca. But I had just bought it and had been sitting.

      A/C failure cause???

      By Somethingclever_2014GM · Posted

      Glad it worked for you. I tried that 1st, about 2 years ago. Didn't help. I also tried doing a hard reset (disconnecting battery for minimum of 30 minutes). Worked a couple times, but after one summer of doing it over and over, that no longer worked.  I was fairly confident it was either the compressor or a failed actuator, but I just couldn't identify which one. Had to research which actuators do what and which last numbers are associated with each.

      Took me FIFTEEN MINUTES to find this. Isn't that a problem? On the mainstream media I can INSTANTLY find 100 articles bashing President Trump ... but when it comes to TRUTH in American corporate news & search engines, it's carefully filtered to support ONE SIDE. A Republic cannot survive like this! Incredible! Even all the AI searchers out there failed as well! ChatGPT said it needed more details on the video that I provided a DIRECT LINK to! I thought AI was the be-all, end-all?? I had to dig it up myself. This should be FRONT PAGE NEWS!!! 🤬   Here's the statement directly from our President:     Glenn Beck's reporting on the operation:   https://glennbeck.com/watch/videos/trump-just-revealed-a-massive-military-secret-that-lowered-gas-prices   In case that link doesn't work, here's the YouTube link:     And another 15 minutes to find this clip out of Glenn Beck's video - the first few seconds is all the corporate media will allow the public to see, since the low IQ people will think Trump said " I love inflation ", and that was the end of it. Taken WAY out of context! Here's that part, plus the 2nd part about the oil smuggling operation:

      Another 6.2L engine failure!

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.
