Rough idle/blue smoke -- fix?
This may help someone.
There is a GM injector harness fix for the title symptoms and it was performed on my truck a year ago. Also ECM reflashed for reduced back pressure in exhaust to help prevent egr codes, my egr was unplugged! imagine that. A month ago my truck started the same thing again, I thought. Called dealer, removed Edge w/ Attitude, hauled to dealer, own a rollback. Service manager drove several times, no problem found except egr codes. SM calls, good guy, says get egr fingerstick and install, clear codes and drive if problem comes back bring back to dealer. Well before fingerstick installed and after Edge reinstalled problem is no longer evident. I felt like a bad connection could be the problem that was removed with removal of the Edge. I tweaked all connectors ever so slightly of the Edge harness and applied electric grease, when Edge reinstalled same day back from dealer, the problem has NOT RECURRED. I now have the fingerstick installed, THANKS JK, and the egr codes do not recur. bob
