i am in need of a mop with sensor for 2004 rx8. help!!

 

Have you gotten the codes for your OMP to make sure it's that? - Have you tried using electrical contact cleaner on the contacts for your OMP just in case something has gotten in it?
(Not trying to question yours or anyone's diagnosis)

If not check the forums for the part out like https://www.rx8club.com/rx-8-parts-s...rt-out-275258/ - Jatmon I can see is US based in WI so maybe works for you? Looks like he has a couple of part outs.
Good luck!
