Default Re: Rcm issues

whitexfire84 "Checking horn fuses yesterday number 6 on the rcm touched the wires to the five plugs and car started to run rough … every time I wiggled them the car would get worse … fan which hasn’t come on in some time I noticed turn on and start spinning near the radiator… wigged again and the car died … started back up when I tried starting it up. Left it alone til today and my wife drove it to work . Now it’s misfiring … shaking at idle and died a few times on her at stop lights. Rcm was replaced already with a brand new one but solder joints have never been touched on it. Emailed “tighed” yesterday and no response yet. Any ideas everyone?"

It sounds like you have bad contacts between the RCM and the wire connections. It has happened on another car, ( I think it was GraphiteGhost) that some of those small end connectors inside the plastic connector needed to be replaced. When you have the RCM in the mail to tighd1 it would be a good time to check all those end fitting electric connectors.
I wouldn't mess around with trying to figure out any other problem until you get the RCM reinstalled in your car and wiggling those wires causes no rough running/misfires and no other noticeable problems like the fan starting up as you mentioned. Get the RCM seated in there correctly, then clear all your codes and start with a clean slate.
PS. Get yourself a can of DeoxIT D5. It is more than a contact cleaner. Really good spray for electronic connections.
