    water temp gauge

    Just changed the PCM with a tune and everything working good except now temp gauge goes down to like 165 intermittently even key on eng off. all wiring good just thinking signal from PCM getting lost/dropped. I am going to put in oem pcm tomorrow to see if this fixes it but just wanted to see what you all thought.

    maybe the pins for the PCM connector aren't all the way in?
