I have twin 5.0L MPI engines. Normally both engines runs at 150 degrees at idle and 160 degrees while running on plane. The port engine is now running cold 120-130 degrees when not on plane. When on plane it very slowly increqdes to 160 and falls quickly when throttles are backed off. The thermostat was changed and the problem persists. The connection into the thermostat housing looks ok. I'm thinking it may be the thermostat sensor. Has anyone else experienced this?
Thanks
