2012 Escalade 6.2 was created by L0st10mm
2012 6.2 Escalade misfire Cylinder 3 swapped spark plug,coil,and spark plug wire. Still had misfire removed valve cover all lifters moving and no play.Checked fuel injector connector with noid light and is good. Did injector balance test on all cylinders 7 start at 70psi and drop to 29pis during test cylinder 3 starts at 70psi and only drops to 47psi. Could it be a bad injector? I'm a beginner and any help would be appreciated.

Sounds like you found it. If you're not confident in the test, and assuming it's not too difficult, you could always move the suspect injector to another cylinder.

No change meaning what exactly?The misfire is still present on cylinder three, or that when repeating the injector balance test, that injector still flow less fuel than the others wherever you placed it, or that cylinder three still flows almost 20psi less than the others even with a different injector in that hole?
