My ECM reads the CTS at 104 then goes down if the as the engine warms up by get this. if I cut the key off the ECM reads the right temperature just before it loses power. I've cleaned all the grounds in the engine bay and put a new CTS in and a new CTS connector (was doing this before I changed connector ).
