hey guys i have an l20b running a stock rebuilt hitachi, i just finished the rebuild and i also swapped from heat riser intake/exhaust to non heat riser, all of the egr has been removed and im having a little bit of tuning trouble.
when the truck is warm i can get it to idle smooth, but when i drive it and i come to a stop sometimes it idles and sometimes it will idle down then quit, its quite annoying and i was wondering if any of you had any tips, i know one guy on here was saying something about the idle and mix screws, tinkering with them both in a certian way but i couldnt make sense of what he was saying, i have set my mix screw to 2-2.5 turns initially and set my idle screw, thanks
