Kohler CV26 EFI missing running rich

I have a Kohler CV26 EFI on a country clipper. Fault code is 34 and 31. Lately it has been missing and bogging down when under load. Misses at idle and full. I replace the plugs, still does it. I have service man for it so I started testing. O2 sensor seems to test ok. As far as I could test the TPS it tested ok until I opened it up to full throtle, my meter went to 0 supposed to be 1800-3000 ohms but I'm not convinced it's the TPS cause it misses at idle also. Any ideas out there as what this could be. As I said there are more tests for the TPS, BUT I'm not sure how to perform them with the TPS mounted as there is no room for probes. Continunity tested ok on the O2 sensor also.
