Interesting situation, the only 2 codes my ECU has ever thrown at me are RM and the Coolant temperature code. Here's the interesting part, they have never been on at the same time. I do have a 6 bolt swap and the car ran fine without any ECU codes until I blew the turbo. Since then I have had RM show up. About a month ago I replaced my manifold/turbo gaskets and all of a sudden NO MORE MISFIRE :) or RM code. I did have the Coolant temp sensor code show up though, I just had some issues with starting the car when this happened and it she ran a bit rich. Turns out I accidently ripped the power wire to the plug. Now I replaced the sensor and fix the wire BUT now I have RM again :( I fixed the wire earlier today so I will have the ECU codes checked ASAP to get the actual Code #'s it throws. Until then has does anyone have any idea what relation these two codes have?

P.S.: I'm thinking of cutting the power wire again because it is very annoying running with a RM code I haven't been able to get rid of for years. I'd rather run a bit rich than with RM :)
 
Quote from RRE 6 bolt swap "Reported problems range from none, to annoying, so be aware. At the time of this writing the most common glitch is an increase in CEL's. The most likely CEL to occur is "Random Misfire" Possible problem sources for phantom misfires are intermittent electrical connections and/or noise in an unshielded wiring harness, harmonic vibrations in the timing belt system, or a bad CAS. OBD-II 2G ECU's were designed to detect misfires from a sensor reading directly from the crank. A simulated crank signal from the CAS may not be accurate enough for some ECU's." Dsmlink has this problem automatically taken care of in their code if you decide to go that route. I think its your best bet
