I'm wondering if the tune has something to do with it???
I also unplugged the exhaust flapper connector for the first time this winter, so maybe the rough idle is due to that???

Trying to diagnose the problem one piece at a time, just plugged the exhaust flapper back in... I'm going to see if that fixes the rough idle...
If not I'll scan for codes and remove the tune...

If anyone has experienced this, any feedback would be appreciated...
Thanks
That definite injectors.

I will post the proper video, how to fix it with minimal cost and replacing a couple of parts to fix the problem without replacing injectors. Sub for the new vid.
