In theory anyway. I don't see how the timing could affect one particular cylinder. Not familiar enough with the V8 so I have to ask. While doing all this work did you have to move the harnesses around some? if so, maybe you disturbed or caused a connection problem in the harness going either to the #5 coil or injector. In a case like this I think I'd try wiggling the harness on that side of the engine with it idling and see if I could duplicate the misfire. If so, then you just try to zero in from there. One other thing that may or may not hold true here. When I was having a really weird misfire problem on my V6, (long story) I called Identifix and the Toyota expert there taught me something I didn't know about Toyotas. You can't trust the misfire monitors. He said they are notoriously inaccurate. Mine was showing simultaneous misfires on two cylinders on opposite banks of the engine. Turned out, only one of them was actually misfiring. If I were you, I'd verify that the misfire is actually on cylinder 5 before I spend too much time on checking it. It probably is on 5 but I'd wanna be sure after what I went through on mine. Good luck.
