2006 silveardo erratic idle
Hello everyone, I have been Researching some issues I have been having and it is starting to kinda scare me. I have a 2006 Silverado lt 2wd ext cab 4.8 ltr truck that, for the most part runs well. However here in the last couple months I have been having an issue with the idle. When I am at a stoplight or sign, I get an unusual idle "miss" that can either be just a little or sometimes even very heavy. The biggest issue I have is It is not throwing any codes, and I can't seem to find any vacuum leaks, or other problems. I have replaced the plugs to no avail. Can anyone help me figure this out please. I have had this in multiple shops and none of them can find anything out of whack on the scanners other than a slightly lean reading at -3 on both banks. please help
thanks ahead of time

Its possible your throttle body is getting very dirty. You can pull it and clean it up rather than replacing it. I'd run some gas treatment, fuel injector cleaner through a few tanks of gas. Then after that, run some cleaner through a tank every 5 or 6 tanks.
This has helped my truck.
Hope this helps!
