Hi I have a 2015 Chev Silverado, 4.3 engine with a new engine put in 100,000km ago as oil pump went on it before. Now I have a miss on cylinder 5. I swapped coils from cylinder 5 to cylinder 1, new spark plugs put in on cylinder 5 and 3, put new spark plug wires on 1,3,&5. Got injectors all cleaned and tested. Checked and replaced the oil pressure filter on it. And still have a steady miss on cylinder 5 still, which is more apparent when the engine warms up. Did a compression test with cylinder 5 being at 130psi and cylinder 1 also being at 130psi and that was engine cold and hot . I am on a total loss of where to go now. Other than replace the engine or rip it all apart. Could use some insight PLEASE. 
 
   Thanks in advance
