2003 X Type 2.5l issues

Hello all. I’m new here and I’m hoping you all can point me in the right direction. I have an 03 with the 2.5. The issue I’m having is that it’s going into limp mode? It shows ransoms misfires. Misfires on 1,3,5.
When I first got it it was doing basically the same thing. I have replaced all 6 coils, plug’s, both bank 2 O2’s, bank 1 upstream. And recently all 6 injectors. This started when I had to full up with 89 octane gas instead of 92. I’m at my Witt’s end.

Check the crankshaft position sensor, accessed by taking off the right front tire. We had the
same issue a few years ago. The sensor was flaky and it caused random misfires. Or the harness
was damaged down there, I can’t remember. But fixing it cleared up like 5 codes!

Changed crankshaft sensor. That cleared most of the issues. Then it came back with a faulty #2 coil. Changed that and it came up with these issues.

Is there a multipin connector that may include that lot and have water in it?

I have looked and checked every connector that I can get to.
