Just replaced the head gasket and installed a eb head and cam, before i replaced the head gasket the truck was running great ,i had already found and fixed the surging problem a few months prior . Well now its back with a extra issue when im coasting in gear between 1800 and 3000 it the will start surging.

i have checked the maf, tps and for vacuum leaks with no results. I never removed the injectors from the fuel rail or the lower intake and the injector wires are in the correct order, timing is between 5 or 7 cant really tell with the idle jumping around. Fuel pressure is good according to the fsm. So is time to send the injectors off to witch hunter or someone else similar or replace them.

 

might be a place to start. this was our hell

that sounds like a different problem mine only acts up at idle and while coasting.
