89 GTUs OMP/MOP Replacement
 

Recently bought an 89 GTUs in running condition but the car is throwing the CEL #27 code for the OMP/MOP being out, car runs but is in limp mode.

My issue I am having is trying to find a legitimate write up on removing and replacing while the engine is in the car. (I could pull the engine, however I don't feel like it is necessary to do this job.) I have been reading posts on here and other places online but they don't appear to have what you need to remove in order to get to this. I have an extra OMP on a running engine that came with the car (this motor was pulled from a running driving car due to bad frame rail rust issues) and replacement lines. I have worked on many cars, this is my first experience with a rotary engine. I have a factory service manual but as far as I can tell there are not any references to the replacement/removal of this (maybe I am looking up the wrong term in the glossary??)

I have searched and searched and searched with not much luck, reading the same articles/posts multiple times before posting here. Any help/links/advice are very much appreciated. Thanks in advance.

It's pretty much the same as the S4.
