Ok so I have a problem with my 97 gsr teg. It's running on 3 cyls. Here is what I have done to get where I am and need help. I have pulled #1 #2 #3 #4 plug wires all have spark so I proceed to check again and #4 has spark as well so I checked injectors same 123 are spraying but num 4 isn't i tried switching injectors around and problem stays at num 4 not spraying. I have pulled engine harness and checked all wires no shorts. I changed my hondata ecu to 3 different others and same problem any help figuring this out would be appreciated
