GOOD MORNING, IN THE WORKSHOP WE HAVE A 500 ABARTH, WHICH WHEN YOU START IT FOR 5 SECONDS GOES TO 4 CYLINDERS, THEN GOES FOR 7 SECONDS TO 3-2 CYLINDERS WITH THE ENGINE LIGHT FLASHING AND THEN RETURNS TO NORMAL. WHILE DRIVING ON THE ROAD, I HAVE NOTED THAT THE LANCE ON THE WATER GAUGE IS RIGHT AT 90°C, ABOUT 1 KM, BUT WHILE CHECKING THE TEMPERATURE WITH THE PC IT IS STILL LOW.
WE ALSO HAVE FAULT CODES P0300: RANDOM IGNITION FAILURE, P303 IGNITION FAILURE CIL. 3,P302 FAILURE TO IGN. CIL 2. EVEN IF THE p30... VARIATE FROM DIAGNOSIS TO DIAGNOSIS CHANGE CYLINDERS.
ON THIS CAR WE HAVE TESTED REPLACEMENTS. THE COIL, SPARK PLUGS, INJECTORS, MEASURED THE COMPRESSIONS AND CHECKED THE BICHIERS AND THEY ARE ALL OK.
HOW CAN YOU HELP ME? in your opinion, what could it be?
THANK YOU THANK YOU
