03 possibly bad injector ?
My 03 runs good, starts good, no miss. No codes with AE. Smokes very little cold but once its warm it burns your eyes at an idle or higher rpm and smokes heavy smoke. FICM voltage tests good and shows good with the AE, no EGR, turbo is not blowing oil. Head gaskets are new with studs. Injector Orings and seals are. No bubbles in the fule filter housing when cranked. So I suspect 1 or 2 bad injectors over fueling. I have done multiple power balance tests tests warm and cold and its almost a straight line at idle, I cant test it above idle with the AE. 6 and 7 show a very slight 80-90 RPM increase in the power balance, the rest are flat.
Questions should I replace these two? I cant seem to figure out where I can shut down an injector the AE so I believe that on a 03 it wont let me. I may try to unplug one at a time to see if it smokes less. Any other tests, ways to isolate?
