98 k-1500 hesitation off idle

So I replaced the upper intake gaskets. Cleaned the throttle body and manifold while it was off. Buttoned it all back up and it didn't do a thing. HMMM. There was a LOT of carbon build up in there. I have a feeling I will be putting a new spider assembly updated version in it.

The number 3 and 4 cylinder misses are still there though, so that is my only thought to single out a couple cylinders.
