2006 6.0L stock
Right after oil and oil filter change (schaeffers 5w40 syn), and fuel filters changed (motorcraft), it developed a misfire when cold. Would start and idle fine, but stumbled under moderate acceleration until fully warmed up. Once warm it runs 100%.
I double checked all filter gaskets...
Shop says 3 injectors are failing.
Can the injectors act funny when cold but fine when warmed up?
Any other thoughts I should follow up on?
Thanks!!
