Cold 6.0 Bucking

[Stroken49s]

When my brother first starts his 03 6.0 its bucking when he first starts and his motor kinda misses until warmed up.

That's normal for the first minute or so when you first start it when it's really cold. How long is it doing this?

[Stroken49s]

Until the engine warms up from what he told me.. I told him to plug it in.. the only thing its only getting like 45-50 here in MS at night... right now

Hows his oil? When was the last time he changed it?

It could be an injector..
