So Idk if this is in the right forum if not please move! Well I just bought a 2003 silverado with 216000 Km with a new tranny. I absolutely love it! Although I live in canada so the winters can be rough, It's a manual floor shift and my 4 low works fine but if I try to go into 4hi any time ( moving, stopped, in neutral ) nothin works, no 4x4 light or a sound like it's even trying to shift and it is pretty annoying having to go to neutral to use 4 low to get up a slight icy hill just to switch back to 2.
Hello I am a 20 year old that has put more money then I should in my truck but its mine so I want to do something that has been done before but isn't something everyone has. I was to take out my stock 4.8L motor and 4L60E tranny and drop a moded 6.0L with a 4L80E. I am a college student so I am seeking for mods and also some of the things I will have to take into consideration. I don't have to much money to do this (like I said I'm in college) so some cost saving mods and ways to this this will be great as well. I also wonder how the rear axel will be holding up if I do this and if I will need to change the gears. This truck is special to me for the fact I bought it off my moms soon to be husband before he passed away a year ago. just trying to build something unique and that he'd be proud of.
I have a 2001 silverado with the 5.3. It has about 153,000 miles and I have been having an issue that I haven't been able to track down. At idle it has a miss at idle, whether it is cold or warm. My knowledge says it is a vacuum leak somewhere that I cant find. There is no miss at any other rpm than idle. Recently as it has been getting colder (sub-30 degrees F) when I first start the pickup it shakes violently at idle, but after it warms up for about 30 seconds it runs as normal. Today when I started it and was warming it up my SES light started blinking, even though it was idling as normal. I shut the truck off because I knew that meant a multiple misfire code. I tried to start the pickup and it would not start. I plugged in my code reader, and I found the code P0300, or multiple misfire. I cleared the code and it started up and ran just as normal, with no issues. I drove it around 30 miles, shutting off an turning it back on numerous times to try and duplicate the issue but the code never came back. I have checked the intake gasket, which seems to be very intact. Where should I look next? Thanks for the help in advance.
Hey all, I can't seem to reliably find the compression on my '14 5.3L. I'm trying to nail this down because I'm quite curious about the fuel debate. I know there are a lot of opinions out there regarding which octane you should use, if it's better for the engine, better for mileage, etc, etc. Well, opinions shouldn't matter here, right? Based on the compression of the motor we should be able to do some basic math and figure out if a higher octane is even being fully burned or not.
Maybe I'm off here...but maybe I'm not! Weigh in!
