Pimpn8

I have an 04 RX8 with 60,000 miles on it. I just replaced the coils, plugs, and plug wires because of the flashing misfire CEL. The battery was just replaced and oil changed. Within a couple of days of doing these repairs, the car went into limp mode with a CEL on but no retrievable codes. After searching the symptoms, I found that the most likely cause was the OMP sensor. So I did the sensor adjustment and got the car to run fine for a week and then it went into limp mode again. I did the adjustment again and it ran fine for 2 days and now its back in limp mode. I have also checked the wiring and don't see any damage. It seems like it is something electrical with the sensor since it has worked by adjusting the sensor the last 2 times. Can you buy the sensor or do I have to buy a whole pump? Is there anything else to check before I replace the pump? I don't know of anyone within 4 hours of me that has any experience with rotaries that can do a compression check or diagnose so any help is very much appreciated.
