Hey guys, newbie here, how's everyone? I'm looking for some help before I start piling some dough into the Duramax, she idles likes bitch at stop lights and some like a chimney, but all good in neutral and park, I've researched for hours and people are saying mixed results of EPR and injectors, I have not had a scan be doing the scan on Friday, has anyone ran into this problem?
LLY idles rough in drive and reverse at stop ligh

Thanks, and yes it does fluctuate up and down, I also should mention that you can smell raw diesel a lot, another question instead of replacing oem FPR has anyone deleted this? Just spoke wih a local diesel performance shop and there is a part made by ppe that eliminates the low side, and is only 40 bucks?
Thoughts from you guys please!
so I replaced all 8 injectors now, I had a bad injector out of the box reading +15, got another one and still rough, sent it into GM dealer came back with balance rates as follows:
cylinder 1 (-2.5)
cylinder 2 (-4.6)
cylinder 3 (5.2)
cylinder 4 (-3.2)
cylinder 5 (-0.6)
cylinder 6 (-0.2)
cylinder 7 (1.4)
cylinder 8 (-1.2)
so cyl 3 is bad of course, I am worried about cyl 2 and possibly 4, these were GB remans and I would not reccommend them at all, any one else have a problem with these?
