Duplicated question

The P1114 is telling you there is an intermittent problem with the temp sensor circuit. The P0300 is random misfire and probably resulting from over rich fuel mixtures triggered by the temp sensor problems. The problem could be the sensor itself or a wiring issue between the sensor and the computer.

Do you have any mileage programmer? You can use it to reset the dash board.

Pull the sensor out, cut the wires then wire them together this will make it think the door is always shut.

Check for fault code and replace sensor with genuine item as after market units are not always compatible with the cpu. Have the cpu reset . You may need a code reading tool for this operation.

that code is usually vacuum leak

need to change sparkplugs and wires, transmission fluid and transmission filter, motor oil and it check gear oil in axle, and check ball joints and u joints
