Had a 2018 Sierra 2500 for a loaner while my 1500 was having warranty work done. We got a couple 0 degree days here in St Louis during the polar vortex and the 2500 went into limp mode and wouldn't allow me to go above 25 mph. CEL came on and a message popped up "Reduced Engine Power". I was 30 miles from the dealer that loaned it to me and they sent someone out and gave me a 2019 Silverado 1500. Next day they towed the 2500 back and found the diesel fuel had "gelled" from the cold temps. Curious, is this common in diesels? I let it warm up for at least 5 minutes before driving as I know diesels need a little more warm up time than gas engines. How could it idle and drive up to 25 mph with the fuel "gelled" as the dealer put it? Didn't shake or sputter, just had the rpm limiter kick in at 25 mph.

Reduced Power 2004 2500HD 8.1L Gas
Squatcher posted a topic in 2000-2014 Silverado & Sierra HDHi, Richard from Pleasant Lake, Michigan. I have a 2004 Chevy 2500HD with the 8.1L Gas, with 44796 mileage, but 7400 hours on the engine. I bought this used from a dealership over a year ago and am now having issues with the truck. I have been having problems with the Yellow Engine symbol showing up and Reduced Power showing in the DIC window. Plus I am hearing what sounds like predetonation/ rattling from the engine when I give it gas. The engine runs ok, but there is more to the noise than a smooth running engine, kinda like a rumbling. Can anyone help me figure out what is causing this? I have had this happen three times so far, once during the summer of 2013, once last December and yesterday 1/19/2015. When it occurred back at the end of December I pulled three codes from my truck. P0220 P0134 P0300. When it occurred last summer, I changed all the plugs and wires to AC-Delco. I found out that if I start, run for a minute and shut down several times, the error goes away and I'm ok. I just need to get this resolved, because I use this to pull out travel trailer. I have run a couple of tanks of premium thru it and added cleaner to the fuel previously. Thanks, Richard 2004 2500HD, 8.1L Gas
