01 7.3 momentary shudder

[BP01.7.3]

Hi everybody I'm new to the forum not my first psd truck or my first 7.3, but first time I've had a problem like this, my truck is an 01 crew cab 7.3 auto 4x4, sometimes it will shudder bad at around 1500 until a certain temperature then it's fine, it doesn't do it at heavy acceleration or does it miss when it's cold and cold starts fine, meybe the ipr? Sorry for the long post
