On the 6L's say it passes a buzz test all 8 and contribution is fine but it runs rough only while cold? As in up until that normal operating range... then once it's "warm" it smooths out like water. Does that mean the injectors are failing? Even though it acts normal at all times once it's warmed up. And is that any different for a 7.3? I heard that meant the injectors were failing, but I don't get how that can be if the engine runs fine once warmed up.
... not trying to hijack... I'm just curious.
