My EGT on my #4 Cyl is reading consistently 300-400 degrees F lower than all the rest of the cylinders on my O-320. It is the same dist from the exhaust as the other sensors. It reads the same as the others at room temp, but is colder than the others as soon as the engine is started.
Cyl head temps on #4 are in line with the others. I have been told that these sensors either work or don't - no middle ground. Could the splice from the sensor to the wiring harness be the culprit? The wire harness to the EMS is thermocouple wire.
Any thoughts appreciated.
