3.4 random miss fire

Hey so I am at a lose I have a 93 with a 3.4 swap out of a 97 t100 it’s been lagging for a while on the scanner shows it trims fuel back tell between 3800 and 4500 rpm’s then kicks it up to 0% trim and miss fire on #1 and #6 then last month it just started bucking real hard died and wouldn’t start towed it home finally started shows random miss fire on all but #4 and lean fuel code I’ve replaced
injectors
Spark plugs
Pcv valve
Crankshaft sensor
Fuel filter
Intake gaskets
Maf sensor
Fuel regulator
Switched plug wires and and coil packs around nothing changed
Did compression test all with in spec tried another ecu didn’t change anything have been thinking fuel pump is fine cuz when it stopped trimming fuel back has good power and pulled hills fine gonna try the water temp sensor on the back of the manifold this weekend but running out of ideas if someone has anything would help thanks in advance!
