Error Code P0305
Does anyone knows how to clear error code P0305. So far I've conducted a fuel injector resistance test and switched the injectors around. It still comes back with P0305 under load. I'm also thinking it's the coil pack I just don't know to test it. Has anyone ever experienced this same issue

Yeah, the quickest way to test is:
1. Clear the code
2. Exchange the coil and the wire with the inner cylinder next to it
3. Do the same drive that produces the CEL
4. If you now have a P0303, then it was the coil or the wire.
If you still have a P0305 then it could be the plug or in the harness to the coil packs on cylinder #5. Also, P03xx codes are misfire codes. A bad or sticking injector doesn't usually generate a misfire code, but would have generated something like a P02xx. In this case, a P0205.
