05 LLY Duramax limp mode repair

This is a little video about my LLY duramax that left me stranded on the interstate because it was in lamp mode tracker mode, I made it to an o'reilly to have it scanned and seen number 8 injector code so when I touched the number 8 pigtail And add the batteries on the hooked to clear any codes it started running good So I hit the road to try to make it home 4 hours away and it kept on giving me on giving me an issue every so ofthey're so often until it finally left me stranded for good about 10 miles from home I was from home didn't matter how I wiggled it it would not run good, When I got it Towed home The next day it started and I was able to narrow it down to the number 8 pigtail and now it is running good and clean
