Multiple cylinder misfire
Trouble Code: P0300
Multiple Cylinder Misfire Detected
Possible Causes:Air leak in the intake manifold, or in the EGR or EVAP system.Base engine mechanical fault that affects two or more cylinders.Erratic or interrupted CKP or CMP Sensor signals.Fuel delivery component fault that affects two or more cylinders. (i.e., a contaminated, dirty or sticking fuel injector).Ignition system problem (coil or plug) in two or more cylinders.Vehicle driven with low fuel pressure or while very low on fuel.
Engine runs rough if it warms up won't start dtc codes p0118 and p0113 just did head gasket and replaced exhaust manifold all new gaskets new plugs wires and coolant engine timing marks are all c
Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113
check engine light code
.P0118
- The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.Potential Symptoms
Symptoms of a P0118 could include:
- Very poor fuel economy
- A no start condition
- Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
- Illumination of MIL
Causes
A code P0118 may mean that one or more of the following has happened:
- A bad connection at the sensor
- An open in the ground circuit between the ECT sensor and the PCM
- A short in the voltage feed between the sensor and the PCM
- A bad PCM (less likely)
- A bad temperature sensor (shorted internally)

Hi Ronald, take the vehicle for a diagnostic read out. Seems you have a problem with a temperature sensor or the cold start up idle. Regards John
