Looking for some advice. When replacing a bad injector on a DT466, do you replace only the bad ones or do you do the whole set? Last week I had one running rough. I found out that the #2 injector was the cause. I also had an inactive code for an open coil on injector #1. Both of these injectors were replaced. It ran great for 3 days and the #3 injector went out. Past practice here has been replacing the $385 injectors one at a time when they go out insteading of doing the whole set for $2300. Any thoughts and opinions would be much appreciated.
I've done one by itself if the budget is really tight, but will fight with the boss to do all 6. Same with glowplugs on engines that need them. You are in there, you already have stuff out of the way, and if one(or 2) failed, then the rest aren't gonna be far behind.
