I have read and understand about injector knocking and white smoke at idle. My problem is the knock comes and goes at times at idle. Above 1200 to 1300 rpm it is completely gone. Ok, bad injector. If i crack the lines at idle all of them are about the same. At idle and at 1200 rpm.
The white smoke i understand at cold idle, but even after warming up the white smoke reappears up to about 1000 rpm. Injectors have about 5k on them and ip about 65k. I recently turned down the fuel because i was getting black smoke above 1200 rpm, loaded or not, even whrn reving it up. I turned it down about 1/2 of a flat. Ip timing is about 1/16th towards the passenger side. Question, injectors or ip or both? 1991 Ford Navistar 7.3 IDI
