    I drive a 2004 GMC Sierra 1500. Yesterday, the truck seemed to take an extra second to start, which wasn't normal. It seemed to have a slight delay, but it did not turnover a bunch before starting. It was enough of a delay for me to notice a difference, though. I then noticed that none of my...

    Hello, I was looking for some advice and this group seemed like the right folks to ask. I have a 2021 1500 AT4. Absolutely love the truck and it is the nicest vehicle I have owned. That said, my check engine light just came on for the third time and I am just shy of 43k miles. The first two...

    I have 2016 Sierra 4x4, 5.3L. A couple years ago I did the cold air intake and cat back exhaust, and a Superchips programmer. Just recently I added Stainless Works long-tube headers with performance cat/Y pipe. Fired it up and the check engine light came on, kicked up code PO420 and PO430. I put...
  4. TurboMax 2.7L I4 Gas
    Been in the shop since November 16 with the p0304 code. Waited 18 days for parts - injector and seal kit, however, this did not resolve the issue. Still getting emissions error. Dealer says GM engineers want to replace the rocker arm first, and if that doesn't work, drop the oil pan and...
  5. Vortec 6000 6.0L V8
    This is my first post here so cut me some slack if anything less than perfect.. Anyway, I recently bought myself a 2013 Silverado 2500, gas 6.0, 4x4 & on the drive home taking the highway I noticed there is little shake/vibration while on the gas when going 40+. Nothing bad at all, just seems to...
  6. Vortec 6000 6.0L V8
    My 2013 Silverado 2500 has been misfiring & jerking under acceleration for a little while now & the CEL finally came on last night at startup. I took it in to Autozone & it showed for P0442, small evap system leak, canister purge valve, with the recommendation of replacing the evap emissions...

    Hey I have a seemingly easy to answer question that I cant seem to figure out. I have had a P0442 code that has been on my dash for about a year. It will leave for awhile (maybe a week) then pop back up. I have done almost everything I can think of, including gas cap, evap purge solenoid valve...
  8. EcoTec 5.3L V8
    (2020 Chevy Silverado LT Reg Cab) Hello After 14 flashing check engine lights and 7 trips to the service center, I finally got the dealership to switch out all the lifters on my truck. Im hoping that will solve this issue. The check engine flash would show a misfire code but they could not...

    So I wanted to add factory remote start to my truck, but the one specific to my vehicle is no longer sold and I couldn't find one available (GM #17801236). So I found GM #22970855 which claimed it would work with a 2010 even though technically it was a 2012 part. In looking at the specs, the...
  10. Vortec 5300 5.3L V8
    This was the 3rd time in 2 weeks it came on so now $465 latter, it still comes on. 2013 Silverado 1500 4 x 4, 4 door. They replaced one of the O2 sensors, said it was dirty then next visit said might switch them around per a note from Chev, cleaned the mass air flow, saying error code is...

    Driving home on the highway, my check engine light started flashing for 10-15 seconds then stopped. Made it home with no issues. Car was running as it always does. I did smack the dash to kill a mosquito right before - was that the reason?
  12. EcoTec 5.3L V8
    2021 Sierra 1500 AT4 (5.3L) purchased brand new 13 mos ago. Have 44k miles. Tonight I’m about 100 miles from home and suddenly the dash lights up like a Christmas tree. Check engine light flashing, ESC warning lamp, another warning lamp with a wrench and a message “ESC SERVICE REQUIRED.” Well...

    anyone know what the issue could be? the moment i press the brake pedal the lights turn off (meaning the battery light and other dash lights alike), but as soon as i accelerate the lights turn back on and gauges don’t work properly? (as you can see in the right hand side) could it be a fuse? a...
  14. TurboMax 2.7L I4 Gas
    I leased a 2022 Silverado 1500 LT Crew Cab with the 2.7L 4-cylinder turbo about three months ago. The day after returning from a 2,000-mile round-trip to Maine towing our travel trailer (which comes in under half of the truck's towing capacity and cargo capability) I was coming back from lunch...
  15. EcoTec 5.3L V8
    Hi- I'm trying to help my fiance get his truck fixed. Long story short - his 2014 Silverado is a driveway ornament. He noticed on one of the rare occasions it was driven this fall that the check engine light was on, but it was intermittent. So, we took it to the dealership to get fixed...
  16. Vortec 4800 4.8L V8
    I switched fuel from 87 which was used for a long time to 93 and got check engine. I checked it a day after and got EVAP code. But a week later i checked it with friends scanner and got 6 codes. One of the codes was U0107 which I’ve seen it may be a ground wire which i hope not but other than...
  17. Vortec 5300 5.3L V8
    Hi! I drive a 2004 GMC Sierra 1500 4x4 5.3. Yesterday, I cleaned my k&n air filter as I bought the truck with it and it was pretty grimey and nasty. Bought the specific kit to clean with the degreaser and spray oil. Figured while I was at it I’d buy a can of maf sensor cleaner. Cleaned my maf...
