P0272 question

2837 Views 3 Replies 3 Participants Last post by  klhansen
e99 F250 7.3L 4x4 ccsb 295000 miles. constant p0272, clear it and it comes right back. it pops up on CCT also. I know I need to compression test it and possibly have the injector rebuilt, but which cylinder is it? I have seen that it is cylinder #4 and I have seen that it is Cylinder #4 in the firing order. Is there a difference? Which cylinder/injector should I be concerned about?

Answered in your other thread.
Since you're getting a contribution test code, that AD probably actually is an AD injector.
