problem is on a 1500 5.7 hemi

still dont know what the problem is
please can anyone help me
it is difficult finding someone whomight be able to fix this in the uk

 

It's been my experience that when a Hemi truck hesitates, has a rough idle, stalls and/or has poor acceleration, 90% it's either adirty TB or a bad EGR valve.
Since you've cleaned the TB, check out the EGR valve...
