When the engine runs at low idle, the temperature of an exhaust manifold port can indicate the condition of a fuel injection nozzle.
A low temperature indicates that no fuel is flowing to the cylinder. An inoperative fuel injection nozzle or a problem with the fuel injection pump could cause this low temperature.
A very high temperature can indicate that too much fuel is flowing to the cylinder. A malfunctioning fuel injection nozzle could cause this very high temperature.
Use Tooling (A) in order to check the exhaust temperature at the exhaust outlet for each cylinder.
Compare the temperature readings for each exhaust outlet. Investigate any difference in the temperature readings.
