GOOD MORNING WE HAVE THIS CAR IN AT THE MIN & ITS RUNNING POOR ON IDLE ALSO FAULT CODES FOR MISFIRE ON NO3 & NO4 KEEP POPPING UP. A WEEK AGO WE FOUND THE TIMING CHAIN SLIPPERS HAD WORN AWAY & THE TIMING WAS OUT BUT ONLY 1 TOOTH! WE REPLACED ALL THE CHAINS & SLIPPERS WITH NEW. NOW IT RUNS OK AT HIGH RPM PUT VERY POOR ON IDLE. WE REPLACED ALL SPARK PLUGS & ALL COIL PACK WITH GEN PARTS ALSO REPLACED THE CRANK SHAFT SENSOR. I HAVE CHECKED ALL THE LIVE DATER & THATS ALL OK  I HAVE DONE A FULL CYLINDER LEAK TEST & THATS ALL OK TO. BUT IT RUNS POOR ON IDLE WHEN WARM & THEN PUTS THE LIGHT ON. THIS CAR IS ALSO ON GAS PUT IT RUNS THE SAME ON GAS & PETROL. I HAVE CHECKED FOR AIR LEAKS WITH ARE SMOKE TESTER. PUT STILL NO JOY HAS ANY ONE GOT ANY MORE INFO PLEASE.
